title: Boolean type not read in?
body: <p>I am doing a project in Java for my COSC 117 class and I get an error on my code saying that my boolean type of "done" is never read in. I cannnot figure out how to fix this. Thank you.</p>

        * This program will play the game of craps. The user will roll the dice and if it is a 7 or 11,
        * they win. If the first roll is a 2, 3 or 12; however, they lose. If it is neither, the user
        * keeps rolling until they roll their first number again or a 7. If they roll their first number
