Any suggestions? It compiles correctly..

At a guess ild say its because your opening System.in twice. try keyboard.close(); or whatever it is cant remember it right now. With scanners u cannot open the same file twice or it will give that error so u need to close one scanner before opening it again with another, tell me if it works otherwise ill look at the code and give u an answer,
