Hey guys! I have a program I am writing that I have gotten stuck on. It compiles fine but when I run it I get several error messages. Illegal format Conversion Exception is one of the error messages. I am stuck and I don't see where the error is. Any insight or guidance would be greatly appreciated! Thank you all in advance!
