If you're developing in NetBeans, you may run into situations in which you define a new file type, you write a displayer for this file type, you make some GUI forms that allow the user to change what's in a file of this type, you add ways of saving files of this type etc. All this functionality is provided by different modules which need to communicate with each other.
