In this chapter, we covered powerful refactoring functionalities in IntelliJ IDEA. By now, you should have a fairly good idea what refactoring in IntelliJ IDEA is all about. Using the actions from the refactoring toolset will help you make code cleaner, more maintainable, and easy to extend. Thanks to its advanced code analysis, IntelliJ IDEA can perform most refactorings automatically, saving significant time. However, it's not only about the speed but also about the confidence you can have with the IDE altering your source code. Most of the time, automatic refactorings performed in IntelliJ IDEA are smart and safe.

Feel free to experiment by selecting targets and refactoring actions. Remember that you can always undo.

Now you know how to make your code refactored and clean, so the next step will be to run it. We will do this in the next chapter.
