I'm doing the culminating project for my intro java class and cannot figure out why I am getting an infinite value for the PercentageCap Calculation. Let me know if you see something in my code that I am missing or I need to look at. The program must have a main class and two seperate classes that feed into it so there is quite a bit of code! I have highlighted in bold where each class starts along with the calculation that I cannot figure out. If you have any additional questions about the program feel free to leave them in the comments.

There's a lot of code, and you don't specify where you're getting the infinite value, but it's likely in one of your divisions - when you divide a double by zero, you get a signed infinity.
Make sure that your dividend is nonzero before dividing.
