There is an issue with my Java program. I need to simulate a craps game, but two methods don't seem to be registering in the program. public boolean update() and public void printreport(). They need to represent the number of games played, percentage of games won and lost , current account balance, percentage increase or decrease in account balance since the session began in the ouput. The account balance in my program doesn't seem to be used even though it was inputed in the Dialog box.
