Introduction
Learn the Java language and how to use JBuilder to create exciting and useful applets, applications, and software components with Teach Yourself JBuilder 2 in 21 Days. Java is now the language of choice for creating applications, applets, and software components for computers and the entire computing enterprise. JBuilder is a powerful integrated development environment that bringsevery level of Java software development within easy reach, including visual programming or RAD (Rapid Application Development). With Java and JBuilder there is no limit placed on your imagination and creativity. The Internet, the World Wide Web, in fact, the entire computing enterprise, are yours to create the Java programs for today and the future. Teach Yourself JBuilder 2 in 21 Days will teachyou all you need to know to start you on your path.

How This Book Is Structured
Teach Yourself JBuilder 2 in 21 Days is intended to be read and absorbed over the course of three weeks. Nevertheless, the pace you keep is up to you. During each week you’ll read seven chapters that present concepts related to Java and JBuilder and the creation of Java software. Each week covers a differentgeneral area of Java software development. The following is an outline of what to expect.

Week 1
During Week 1, you’re introduced to the Java language and the JBuilder integrated development environment. You create Java applications and applets using JBuilder and use JBuilder’s rapid application development (RAD) capabilities including visual programming.

Day 1
Day 1, “Introduction to JBuilder,”explains what Java is, how it relates to JBuilder, and how to install JBuilder properly.

Day 2
Day 2, “Java Basics,” shows you the building blocks of your Java programs, such as variables, types, expressions, operators, arrays, strings, conditionals, and loops.

Day 3
Day 3, “Java Intermediate,” discusses classes and objects and how they relate to each other. You also explore behaviors andattributes.

Day 4
Day 4, “Java Advanced,” discusses protection for class variables and methods, constant variables, classes that can’t be subclassed, and methods that can’t be overridden.

Day 5
Day 5, “JBuilder IDE,” examines JBuilder’s extensive menu system and shows you how to customize the JBuilder integrated development environment.Day 6
Day 6, “User Interface Design,” shows you the UI Designer, the Component Palette, and the Java Abstract Windowing Toolkit (AWT).

Day 7
Day 7, “JavaBeans Component Library,” concludes Week 1 with an exploration of the Component Palette, which presents tabbed pages containing a wide range of JavaBeans software components that you can use in your JBuilder visual programming, or RAD,projects.

Week 2
During Week 2 you dig into building solid Java software, whether it be applets, applications, or software components. All of the elements you learned about Java and JBuilder in Week 1 come together in Week 2, enabling you to create Java programs.

Day 8
Day 8, “Applets, Applications, and Wizards,” begins Week 2 by showing you how to create Java applications, including how topass arguments to a Java program from a command line.

Day 9
Day 9, “Graphics, Fonts, and Multimedia,” discusses how the graphics system works in Java. You explore the Graphics class and Java coordinate system used to draw to the screen. You also see how applets paint and repaint to a window.

Day 10
Day 10, “Streams and I/O,” explains how you create, use, and detect the end of input streams.You learn how to use and nest filtered input streams. And you learn how to create, use, and close output streams.
