Chance Game Java: Need Help Getting it To Run

[coder752]

I need help, it won't run. It only prints my message I put in main. What's wrong? Please help.

It compiles fine, and it just gives me an exception in thread "main" error.

import java.util.Random;

public class Dice{


//create random number generator for roling the dice.
        private Random random = new Random();

//enumeration with constants that stand for the game status
        private enum Status{CONTINUE, WON, LOST};

//simulates a game of craps
public void play(){

        Status gameStatus; //Can contain CONTINUE, WON, or LOST
        int myPoint = 0; //Point if user doesn't win or lose on first try.

        //srand((unsigned)time(NULL));
        int sum=TwoDice();

        // Cases determined on first roll.
        switch(sum)
        {
                case 7:
