Looking for inspiration for assignment

Question

Hi there. For an assignment of a java training I need to make a java program but I can't find the inspiration of what to make. So does someone has an idea?
the only need is that it has at least 4 classes.
maybe someone did something before and can help me. I'm not looking for the code just the idea.

thanks in advance
