As you can see, debugging in IntelliJ IDEA is very handy. After reading this chapter, you know how to set up the debugger, place and manage the breakpoints, and look under the hood (that is, inspecting variables, adding and tracking watches, and evaluating expressions). Searching for bugs will be easy and effective.

You now know how to set up a project and unleash the power of the state-of-the art code editor. You can define a runtime or debug configuration to execute the application. Well, this should be enough to get you going. However, there's some more—version control. You can probably work on your software in the team and use a version control system, such as SVN or GIT. Even if you work alone, having version control set up is a great idea. IntelliJ IDEA provides first-class support for a version control system such as SVN or GIT. We are going to cover this subject in the next chapter.
