For example, to add two numbers, you might have to write an instruction in binary code as follows: machine language 1. Moreover, programs written in machine language are very difficult to read and modify. For this reason, assembly language was created in the early days of computing as an alternative to machine languages.

Assembly language uses a short descriptive word, known as a mnemonic, to represent each of the ­machine-language instructions. For example, the mnemonic add typically means to add numbers, and sub means to subtract numbers. To add the numbers 2 and 3 and get the result, you might write an instruction in assembly code as follows: assembly language add 2, 3, result Assembly languages were developed to make programming easier. However, because the computer cannot execute assembly language, another program—called an assembler—is used to translate assembly-language programs into machine code, as shown in Figure 1. Writing code in assembly language is easier than in machine language. However, it is still tedious to write code in assembly language. add 2, 3, result Machine-Code File Assembler Figure 1. corresponds to an instruction in machine code. Writing in assembly language requires that you know how the CPU works. Assembly language is referred to as a low-level language, because assembly language is close in nature to machine language and is machine dependent.

low-level language 1. They are platform independent, which means that you can write a program in a high-level language and run it in different types of machines. High-level languages are similar to English and easy to learn and use. The instructions in a high-level programming language are called statements. Table 1.

Visual Basic Visual Basic was developed by Microsoft. Enables the programmers to rapidly develop Windows-based applications. indd 8 A program written in a high-level language is called a source program or source code. Because a computer cannot execute a source program, a source program must be translated into machine code for execution. The translation can be done using another programming tool called an interpreter or a compiler. Note a statement from the source code may be translated into several machine instructions. High-Level Source File Output Interpreter a High-Level Source File Machine-Code File Compiler Output Executor b Figure 1. b A compiler translates the entire source program into a machine-language file for execution. What is an assembly language?

What is an assembler? What is a high-level programming language? What is a source program? What is an interpreter? What is a compiler? What is the difference between an interpreted language and a compiled language? Check Point 1. The popular operating systems for general-purpose computers are Microsoft Windows, Mac OS, and Linux. Application programs, such as a web browser or a word processor, cannot run unless an operating system is installed and running on the computer. Key Point operating system OS User Application Programs Operating System Hardware Figure 1. An operating system must also ensure different programs and users working at the same time do not interfere with each other. In addition, the OS is responsible for security, ensuring unauthorized users and programs are not allowed to access the system. Multiprogramming allows multiple programs such as Microsoft Word, E-mail, and web browser to run simultaneously by sharing the same CPU. As a result, it is idle most of the time—for example, while waiting for data to be transferred from a disk or waiting for other system resources to respond.

A multiprogramming OS takes advantage of this situation by allowing multiple programs to use the CPU when it would otherwise be idle. For example, multiprogramming enables you to use a word processor to edit a file at the same time as your web browser is downloading a file. Multithreading allows a single program to execute multiple tasks at the same time. For instance, a word-processing program allows users to simultaneously edit text and save it to a disk. In this example, editing and saving are two tasks within the same program. These two tasks may run concurrently. Multiprocessing is similar to multithreading. The difference is that multithreading is for running multithreads concurrently within one program, but multiprocessing is for running multiple programs concurrently using multiple processors.

multiprogramming multithreading multiprocessing Check Point 1. List some popular operating systems. indd 10 Java is a powerful and versatile programming language for developing software running on mobile devices, desktop computers, and servers. This book introduces Java programming. Java was developed by a team led by James Gosling at Sun Microsystems. Sun Microsystems was purchased by Oracle in Originally called Oak, Java was designed in for use in embedded chips in consumer electronic appliances. For the history of Java, see www. Java has become enormously popular. Its rapid rise and wide acceptance can be traced to its design characteristics, particularly its promise that you can write a program once and run it ­anywhere. As stated by its designer, Java is simple, object oriented, distributed, ­interpreted, robust, secure, architecture neutral, portable, high performance, multithreaded, and dynamic. For the anatomy of Java characteristics, see liveexample.

Java is a full-featured, general-purpose programming language that can be used to develop robust mission-critical applications. It is employed not only on desktop computers, but also on servers and mobile devices. Today, more than 3 billion devices run Java. Most major companies use Java in some applications. Most server-side applications were developed using Java. Java was used to develop the code to communicate with and control the robotic rover on Mars. The software for Android cell phones is developed using Java. Java initially became attractive because Java programs can run from a web browser. Such programs are called applets. Today applets are no longer allowed to run from a Web browser due to security issues.

Java, however, is now very popular for developing applications on web servers. These applications process data, perform computations, and generate dynamic webpages. Many commercial Websites are developed using Java on the backend. Which company owns Java now? The JDK is the software for compiling and running Java programs. An IDE is an integrated development environment for rapidly developing programs. Computer languages have strict rules of usage. If you do not follow the rules when writing a program, the computer will not be able to understand it. The Java language specification and the Java API define the Java standards.

You can find the complete Java language specification at docs. The application program interface API , also known as library, contains predefined classes and interfaces for developing Java programs. The API is still expanding. Java is a full-fledged and powerful language that can be used in many ways. The applications can run on desktop. Key Point Java language specification API library Java SE, EE, and ME This book uses Java SE to introduce Java programming. Java SE is the foundation upon which all other Java technology is based. There are many versions of Java SE. Oracle releases each version with a Java Development Toolkit JDK.

For Java 11, the Java Development Toolkit is called JDK The JDK consists of a set of separate programs, each invoked from a command line, for compiling, running, and testing Java programs. The program for running Java programs is known as Java Runtime Environment JRE. Instead of using the JDK, you can use a Java development tool e. Editing, compiling, building, debugging, and online help are integrated in one graphical user interface. You simply enter source code in one window or open an existing file in a window, and then click a button or menu item or press a function key to compile and run the program.

What does JDK stand for? What does JRE stand for? What does IDE stand for? Are tools like NetBeans and Eclipse different languages from Java, or are they dialects or extensions of Java? console input console output A Java program is executed from the main method in the class. on the console. The word console is an old computer term that refers to the text entry and display device of a computer. Console input means to receive input from the keyboard, and console output means to display output on the monitor. The program is given in Listing 1. Listing 1. on the console System. println "Welcome to Java! indd 12 Note the line numbers are for reference purposes only; they are not part of the program. Line 1 defines a class.

Every Java program must have at least one class. Each class has a name. By convention, class names start with an uppercase letter. In this example, the class name is Welcome. Line 2 defines the main method. The program is executed from the main method. A class may contain several methods. The main method is the entry point where the program begins execution. A method is a construct that contains statements. The main method in this program contains the System. println statement. This statement displays the string Welcome to Java! on the console line 4. String is a programming term meaning a sequence of characters.

A string must be enclosed in double quotation marks. Every statement in Java ends with a semicolon ; , known as the statement terminator. Keywords have a specific meaning to the compiler and cannot be used for other purposes in the program. Other keywords in this program are public, static, and void. Line 3 is a comment that documents what the program is and how it is constructed. Comments help programmers to communicate and understand the program. They are not programming statements, and thus are ignored by the compiler. In Java, each block begins with an opening brace { and ends with a closing brace }. Every class has a class block that groups the data and methods of the class. Similarly, every method has a method block that groups the statements in the method. Blocks can be nested, meaning that one block can be placed within another, as shown in the following code: public class Welcome { public static void main String[] args { System.

Whenever you type an opening brace, immediately type a closing brace to prevent the missing-brace error. Most Java IDEs automatically insert the closing brace for each opening brace. match braces Caution Java source programs are case sensitive. It would be wrong, for example, to replace main in the program with Main. You have seen several special characters e. They are used in almost every program. The most common errors you will make as you learn to program will be syntax errors. Like any programming language, Java has its own syntax, and you need to write code that conforms to the syntax rules. If your program violates a rule—for example, if the semicolon is missing, a brace is missing, a quotation mark is missing, or a word is misspelled—the Java case sensitive special characters common errors syntax rules Table 1. Opening and closing parentheses Used with methods. Try to compile the program with these errors and see what the compiler reports.

Note You are probably wondering why the main method is defined this way and why System. is used to display a message on the console. For the time being, simply accept that this is how things are done. Your questions will be fully answered in subsequent chapters. The program in Listing 1. Once you understand the program, it is easy to extend it to display more messages. For example, you can rewrite the program to display three messages, as shown in Listing 1. java 1 2 3 4 5 6 7 class main method display message public class WelcomeWithThreeMessages { public static void main String[] args { System. println "Programming is fun! println "Fundamentals First" ; System. println "Problem Driven" ; } } Programming is fun! Fundamentals First Problem Driven Further, you can perform mathematical computations and display the result on the console.

java 1 2 3 4 5 6 class main method compute expression public class ComputeExpression { public static void main String[] args { System. print " println println System. As you can see, it is a straightforward process to translate an arithmetic expression to a Java expression. We will discuss Java expressions fur­ ther in Chapter 2. indd 14 1. List some Java keywords. What is the case for Java keywords? Is the comment ignored by the compiler? How do you denote a 1. What is the statement to display a string on the console? Show the output of the following code: public class Test { public static void main String[] args { System. println "3. println 3. java file and compile it into a. class file. class file is executed by the Java Virtual Machine JVM. You have to create your program and compile it before it can be executed. This process is repetitive, as shown in Figure 1. If your program has compile errors, you have to modify the program to fix them, then recompile it.

If your program has runtime errors or does not produce the correct result, you have to modify the program, recompile it, and execute it again. You can use any text editor or IDE to create and edit a Java source-code file. This section demonstrates how to create, compile, and run Java programs from a command window. Sections 1. From the command window, you can use a text editor such as Notepad to create the Java source-code file, as shown in Figure 1. String[] 0 getstatic 2 … 3 ldc 3 5 invokevirtual 4 … 8 return Compile Source Code e. java If compile errors occur Stored on the disk Bytecode Run Bytecode e. Result If runtime errors or incorrect result Figure 1.

Note The source file must end with the extension. java and must have the same exact name as the public class name. For example, the file for the source code in Listing 1. java, since the public class name is Welcome. file name Welcome. java, A Java compiler translates a Java source file into a Java bytecode file. The following command compiles Welcome. java: compile javac Welcome. java Note You must first install and configure the JDK before you can compile and run programs. See Supplement I. A, Installing and Configuring JDK 11, for how to install the JDK and set up the environment to compile and run Java programs. If you have trouble compiling and running programs, see Supplement I. B, Compiling and Running Java from the Command Window. This supplement also explains how to use basic DOS commands and how to use Windows Notepad to create and edit files.

All the supplements are accessible from the Companion Website. Supplement I. B Supplement I. class extension. Thus, the preceding command generates a file named Welcome. class, as shown in Figure 1. The Java language is a high-level language, but Java bytecode is a low-level language. The bytecode is similar to machine instructions but is architecture neutral and can run on any platform that has a Java Virtual Machine JVM , as shown in Figure 1. Rather than a physical machine, the virtual machine is a program that interprets Java bytecode. Java source code is compiled into Java bytecode, and Java bytecode is interpreted by the JVM.

Your Java code may use the code in the Java library. The JVM executes your code along with the code in the library. Java Bytecode generates Welcome. class Java bytecode executable file Ja Java Compiler executed by JVM tual Mac Vir h va e in Welcome. java Java sourcecode file compiled by Any Computer Library Code a b Figure 1. b Java bytecode can be executed on any computer with a Java Virtual Machine. You can execute the bytecode on any platform with a JVM, which is an interpreter. It translates the individual instructions in the bytecode into the target machine language code one at a time, rather than the whole program as a single unit. Each step is executed immediately after it is translated. The following command runs the bytecode for Listing 1. The compiler generates the Welcome. class file, and this file is executed using the java command. class in the command line when executing the program. Use java ClassName to run the program.

If you use java ClassName. class in the command line, the system will attempt to fetch ClassName. java ClassName Note In JDK 11, you can use java ClassName. java to compile and run a single-file source code program. This command combines compiling and running in one command. A single-file source code program contains only one class in the file. This is the case for all of our programs in the first eight chapters. Tip If you execute a class file that does not exist, a NoClassDefFoundError will occur. If you execute a class file that does not have a main method or you mistype the main method e. NoClassDefFoundError NoSuchMethodError Note When executing a Java program, the JVM first loads the bytecode of the class to memory using a program called the class loader.

If your program uses other classes, the class loader dynamically loads them just before they are needed. Java enforces strict security to make sure Java class files are not tampered with and do not harm your computer. Pedagogical Note Your instructor may require you to use packages for organizing programs. For example, you may place all programs in this chapter in a package named chapter 1. For instructions on how to use packages, see Supplement I. F, Using Packages to Organize the Classes in the Text. use package Check Point 1. What are the input and output of a Java compiler? What is the command to compile a Java program? What is the command to run a Java program? What is the JVM? Can Java run on any machine? What is needed to run Java on a computer? If a NoClassDefFoundError occurs when you run a program, what is the cause of the error?

If a NoSuchMethodError occurs when you run a program, what is the cause of the error? Programming style deals with what programs look like. A program can compile and run properly even if written on only one line, but writing it all on one line would be a bad programming style because it would be hard to read. Documentation is the body of explanatory remarks and comments pertaining to a program. Programming style and documentation are as important as coding. Good programming style and appropriate documentation reduce the chance of errors and make programs easy to read. This section gives several guidelines. For more detailed guidelines, see Supplement I. C, Java Coding Style Guidelines, on the Companion Website. indd 18 Include a summary at the beginning of the program that explains what the program does, its key features, and any unique techniques it uses. In a long program, you should also include comments that introduce each major step and explain anything that is difficult to read.

It is important to make comments concise so that they do not crowd the program or make it difficult to read. For more information, see Supplement III. X, javadoc Comments, on the Companion Website. These comments must precede the class or the method header in order to be extracted into a javadoc HTML file. To see an example of a javadoc HTML file, check out liveexample. Its corresponding Java code is shown in liveexample. Java can read the program even if all of the statements are on the same long line, but humans find it easier to read and maintain code that is aligned properly. Indent each subcomponent or statement at least two spaces more than the construct within which it is nested. A single space should be added on both sides of a binary operator, as shown in a , rather in b.

There are two popular styles, next-line style and end-of-line style, as shown below. public class Test { public static void main String[] args public class Test { public static void main String[] args { System. println "Block Styles" ; { } System. println "Block Styles" ; } } } Next-line style End-of-line style The next-line style aligns braces vertically and makes programs easy to read, whereas the end-of-line style saves space and may help avoid some subtle programming errors. Both are acceptable block styles. The choice depends on personal or organizational preference. You should use a block style consistently—mixing styles is not recommended. This book uses the end-of-line style to be consistent with the Java API source code. Use the end-of-line brace style. println "Welcome to Java" ; } } 1.

Syntax errors result from errors in code construction, such as mistyping a keyword, omitting some necessary punctuation, or using an opening brace without a corresponding closing brace. For example, the program in Listing 1. java 1 2 3 4 5 public class ShowSyntaxErrors { public static main String[] args { System. Since a single error will often display many lines of compile errors, it is a good practice to fix errors from the top line and work downward. Fixing errors that occur earlier in the program may also fix additional errors that occur later. Compile Figure 1. In the first few weeks of this course, you will probably spend a lot of time fixing syntax errors. Soon you will be familiar with Java syntax, and can quickly fix syntax errors. indd 20 Runtime errors are errors that cause a program to terminate abnormally. They occur while a program is running if the environment detects an operation that is impossible to carry out.

Input mistakes typically cause runtime errors. An input error occurs when the program is waiting for the user to enter a value, but the user enters a value that the program cannot handle. For instance, if the program expects to read in a number, but instead the user enters a string, this causes data-type errors to occur in the program. This happens when the divisor is zero for integer divisions. For instance, the program in Listing 1. java public class ShowRuntimeErrors { public static void main String[] args { System. Errors of this kind occur for many different reasons. For example, suppose you wrote the program in Listing 1. java 1 2 3 4 5 6 public class ShowLogicErrors { public static void main String[] args { System. print "Celsius 35 is Fahrenheit degree " ; System.

It should be To get the correct result, you need to use 9. In general, syntax errors are easy to find and easy to correct because the compiler gives indications as to where the errors came from and why they are wrong. Runtime errors are not difficult to find, either, since the reasons and locations for the errors are displayed on the console when the program aborts. Finding logic errors, on the other hand, can be very challenging. In the upcoming chapters, you will learn the techniques of tracing programs and finding logic errors. Each opening brace must be matched by a closing brace. A common error is missing the closing brace. To avoid this error, type a closing brace whenever an opening brace is typed, as shown in the following example: public class Welcome { } Type this closing brace right away to match the opening brace If you use an IDE such as NetBeans and Eclipse, the IDE automatically inserts a closing brace for each opening brace typed.

Common Error 2: Missing Semicolons Each statement ends with a statement terminator ;. Often, a new programmer forgets to place a statement terminator for the last statement in a block, as shown in the following example: public static void main String[] args { System. println "Problem Driven" } Missing a semicolon Common Error 3: Missing Quotation Marks A string must be placed inside the quotation marks. Often, a new programmer forgets to place a quotation mark at the end of a string, as shown in the following example: System. println "Problem Driven ; Missing a quotation mark If you use an IDE such as NetBeans and Eclipse, the IDE automatically inserts a closing quotation mark for each opening quotation mark typed. Common Error 4: Misspelling Names Java is case sensitive. Misspelling names is a common error for new programmers. For example, the word main is misspelled as Main and String is misspelled as string in the following code: public class Test { public static void Main string[] args { System.

Other titles: Introduction to Java programming and data structures Description: Twelfth edition. Comprehensive version Hoboken, NJ : Pearson, Eleventh edition. Comprehensive version. Includes bibliographical references and index. Identifiers: LCCN ISBN paperback Subjects: LCSH: Java Computer program language Classification: LCC QA J38 L52 DDC This edition has been substantially enhanced in presentation, organization, examples, exercises, and supplements. The book is fundamentals first by introducing basic programming concepts and techniques before designing custom classes.

The fundamental concepts and techniques of selection statements, loops, methods, and arrays are the foundation for programming. Building this strong foundation prepares students to learn object-oriented programming and advanced Java programming. This book teaches programming in a problem-driven way that focuses on problem solving rather than syntax. We make introductory programming interesting by using thought-­ provoking problems in a broad context. The central thread of early chapters is on problem solving. Appropriate syntax and library are introduced to enable readers to write programs for solving the problems. To support the teaching of programming in a problem-driven way, the book provides a wide variety of problems at various levels of difficulty to motivate students. To appeal to students in all majors, the problems cover many application areas, including math, science, business, financial, gaming, animation, and multimedia. The book seamlessly integrates programming, data structures, and algorithms into one text.

It employs a practical approach to teach data structures. We first introduce how to use various data structures to develop efficient algorithms, and then show how to implement these data structures. Through implementation, students gain a deep understanding on the efficiency of data structures and on how and when to use certain data structures. Finally, we design and implement custom data structures for trees and graphs. The book is widely used in the introductory programming, data structures, and algorithms courses in the universities around the world. This comprehensive version covers fundamentals of programming, object-oriented programming, GUI programming, data structures, algorithms, concurrency, networking, database, and Web programming. It is designed to prepare students to become proficient Java programmers. A brief version Introduction to Java Programming, Brief Version, Twelfth Edition is available for a first course on programming, commonly known as CS1.

The brief version contains the first 18 chapters of the comprehensive version. An AP version of the book is also available for high school students taking an AP Computer Science course. The best way to teach programming is by example, and the only way to learn p­ rogramming is by doing. Basic concepts are explained by example and a large number of exercises with various levels of difficulty are provided for students to practice. For our programming courses, we assign programming exercises after each lecture. Our goal is to produce a text that teaches problem solving and programming in a broad context using a wide variety of interesting examples.

Daniel Liang [email protected] www. To help instructors design the courses based on this book, we provide sample syllabi to identify the Knowledge Areas and Knowledge Units. The ­sample syllabi are for a three semester course sequence and serve as an example for institutional ­customization. The sample syllabi are accessible from the Instructor Resource Website. Many of our users are from the ABET-accredited programs. A key component of the ABET accreditation is to identify the weakness through continuous course assessment against the course outcomes. We provide sample course outcomes for the courses and sample exams for measuring course outcomes on the ­Instructor Resource Website.

This edition is completely revised in every detail to enhance clarity, presentation, content, examples, and exercises. Examples are improved and simplified by using the new features in Java 9, 10, The examples are revised. The user interfaces in the examples and exercises are now resizable and displayed in the center of the window. This is consistent with the Java API and is more useful and flexible. These exercises are available for instructors only. Please visit www. This will help them determine whether they have met the objectives after ­completing the chapter. The book uses many small, simple, and stimulating examples to demonstrate important ideas. It helps them reinforce the key concepts they have learned in the chapter. The trick of learning programming is practice, practice, and practice. To that end, the book provides a great many exercises. Additionally, more than programming exercises with solutions are provided to the instructors on the Instructor Resource Website.

These exercises are not printed in the text. Note Provides additional information on the subject and reinforces important concepts. Tip Teaches good programming style and practice. Caution Helps students steer away from the pitfalls of programming errors. Design Guide Provides guidelines for designing programs. Flexible Chapter Orderings The book is designed to provide flexible chapter orderings to enable GUI, exception ­handling, recursion, generics, and the Java Collections Framework to be covered earlier or later. The ­diagram on the next page shows the chapter dependencies. Organization of the Book The chapters can be grouped into five parts that, taken together, form a comprehensive introduction to Java programming, data structures and algorithms, and database and Web programming. Because knowledge is cumulative, the early chapters provide the conceptual basis for understanding programming and guide students through simple examples and exercises; subsequent chapters progressively present Java programming in detail, culminating with the development of comprehensive Java applications.

The appendixes contain a mixed bag of topics, including an introduction to number systems, bitwise operations, regular expressions, and enumerated types. indd 6 Chapter 8 Multidimensional Arrays Chapter 28 Graphs and Applications Note: Chapters 31—44 are bonus chapters available from the Companion Website.
