The code is in my first method, payCalc();. my NoSuchElementException is catching every time i run it. The program will prompt the menu, and if you choose case 1 it will prompt for the names, then loop back to the menu. I've tried removing various things or commenting things out, but i'm just not sure what is causing the problem. This is my first program working with try/catch and throws so possibly it is a misunderstanding of the workings on my part.
