书籍简介
Introduction
This book takes you on a guided tour to building applications with the WebSphere Studio Visual Editor for Java and JavaBeans. Along the way, you’ll learn the basics of how to develop Java applets and applications, as well as more advanced topics such as using relational databases and eXtensible Markup Language (XML) documents to store your application data. By the end of the tour you’ll be able to use WebSphere Studio to build your own applications and you’ll understand why JavaBeans are so useful for application programming.
If you’re new to Java and Java development environments, that’s OK. This book assumes you have some basic knowledge of the Java programming language, but you certainly don’t need to be an expert to follow the tour. You do need to be running one of the Windows operating systems, and as long as you’re comfortable with Windows, the Internet, and Web browsers, you’re ready to learn Java.
If you are already familiar with Java and Java development environments, that’s OK, too. You’ll still benefit from going through the tour, because it will teach you many of the WebSphere Studio features that will let you build your Java applications easier and faster.
This book uses the “show and tell” approach. If you flip through the pages, you’ll notice that they are loaded with pictures showing how your applications should look at each step along the way. In addition, we’ve included two CDs that contain all the tools you’ll need to follow along with the lessons.
Why Java?
Java is considered the language of the Internet. It combines two important advances in computer science: object orientation and platform independence. Object orientation means that the programming language models real-world components and behavior. You organize your programs into objects with certain properties and define the activities that the objects can perform. Complex behavior is hidden in the implementation of the object, letting you just connect the object to other objects. Secondly, Java is platform-independent, which means that you can create programs on a Windows machine and be confident that the program will work in any environment that Java runs in.
In the past few years the use of Java has exploded. It has expanded well beyond its original main purpose of providing dynamic Web pages, to a full server-side programming language. It enables the development of complex Internet functionality, such as querying legacy databases, enabling business-to-business Web commerce, and providing interactive Web communications. Because it’s based on open standards, all Java programs use a common API. This means that you can reuse other Java components and easily snap them into your programs.
