What you need for this book

You will need a Mac or PC, running OS X, MS Windows, or Linux, to be able to set up and run IntelliJ IDEA. To learn the presented features, you will also need the tool itself, of course. You can use the free 30-day trial of Ultimate Edition or use the Community Edition, which is available free of charge. We will flag the differences and let you know what features are not available in the free version of the IDE. You can read how to get it in Chapter 1, Get to Know Your IDE, Fast.
