Appendix A. The Eclipse IDE

This is a book about the Java language and as such we’ve tried to avoid talking too much about specific tools and applications. But of course, we’ve had to make some exceptions where the real world of Java programming and de facto standards dictate. An example of this is the Apache Ant build tool that we discussed briefly in Chapter 15. Ant has become a de facto standard for building Java applications and something that every Java programmer should at least be aware of. A more challenging topic to cover is that of Java integrated development environments (IDEs).

A wide array of Java IDEs are available, with greatly varying features. Like all applications with a great deal of interest, IDEs are constantly changing and improving. Throughout this book, rather than distract from the topic at hand with screenshots of one IDE or another, we’ve chosen to refer only to simple command-line tools. In the real world, many if not most Java developers now use IDEs, so our approach paints a bit of a skewed picture of the process. We aim to rectify the situation here by introducing the Eclipse IDE and showing how to use it to load and explore all of the example code from this book.
