    Default Java Programming - Dice Game Help!

    Hi guys, first time poster here. I'm a beginner at java and I'm having some serious difficulty with this code. The problem is to create a dice game, that has two dice, that you roll, in turns with the computer. Here are the rules for the game:

    1.) You must accumulate 100 points to win.
    2.) If you roll a 1, you loose all your points for your round and your turn.
    3.) If you roll two 1's, you loose ALL your total points and your turn.
    4.) You can voluntarily give up your turn.
    5.) The computer plays by the same rules, but if it rolls 20 points in a round, it must give up its turn
    6.) You must roll at least once in a round, you cannot just give up dice

    I'm having the most trouble right now with being able to pass the turns back and fourth between the computer and the player. The program complies but never acts like I want it to. I've spent soooo much time on this. Any help would be greatly appreciated. THANKS!

     
    public class pairOfDice

        	faceValue2 = 1;

    never acts like I want it to.
    Please explain what it does and what you want it to do differently.
    Post the console output and add some comments explaining what you want to be different.
    If you don't understand my answer, don't ignore it, ask a question.

    The program is designed to ask the user if it wants to play a dice game and roll 2 dice. The user wants to get to 100 points, but it he/she roll a 1 on one of the die, or two 1's, then they loose there points and there turn. They are asked after every turn if they want to roll again (except when they roll a 1 or two 1's) When they dont want to roll again they to give the dice to the computer, which plays by the same rules except it automatically rolls again, until it reaches 20 points (if it doesnt get a 1 or two 1's) and then gives the dice but to the user.

    I cant seem to get the program to correctly pass back and fourth the turns between the computer and the user.

    What does the console output look like? Can you post that and add comments where the problem is?
