Integrated development environments provide us with services. The most basic service is that you can edit files with them, but they also help build the code, find bugs, run the code, deploy to the application server in development mode, debug, and so on. In the following sections, we will look at these features. I will not give an exact and precise introduction on how to use one or the other IDE. A book like this is not a good medium for such a tutorial.

IDEs differ on menu placement, keyboard shortcuts, and they may even change as newer versions are released. It is best to look at the actual IDE tutorial video or online help. Their features, on the other hand, are very similar. IntelliJ has the video documentation at https://www.jetbrains.com/idea/documentation/.
