    (Game: craps) Craps is a popular dice game played in casinos. Write a program to play a variation of the game, as follows: Use a class to define the method getDice, and make sure that the method is overloadable. Roll two dice. Each die has six faces representing values 1, 2, …, and 6, respectively. Check the sum of the two dice. If the sum is 2, 3, or 12 (called craps), you lose; if the sum is 7 or 11 (called natural), you win; if the sum is another value (that is, 4, 5, 6, 8, 9, or 10), a point is established. Continue to roll the dice until either a 7 or the same point value is rolled. If 7 is rolled, you lose. Otherwise, you win.

    Your program acts as a single player. Here are some sample runs.

    You rolled 5 + 6 = 11
    You win

    You rolled 1 + 2 = 3
    You lose

    You rolled 4 + 4 = 8
    point is 8
    You rolled 6 + 2 = 8
    You win

    You rolled 3 + 2 = 5
    point is 5
    You rolled 2 + 5 = 7
    You lose

    Well that's a shame. I guess you now have to fix it. Since we do not read minds and have no idea what the error is, nobody can help you.

    You can try this code!
    //Filename: CrapsGame.java

    import java.util.*;

    public class CrapsGame
    {
    public static void main(String[]args)
    {
    int die1,die2;

    die1 = (int)(Math.random()*6 + 1);
    die2 = (int)(Math.random()*6 + 1);

    int marker = die1 +die2;
    System.out.println("Initial roll " + marker);

    if(marker == 7 || marker ==11)
    {
    System.out.println(" You win! ");
    }
    else if(marker == 2|| marker ==3 || marker ==12)
    {
    System.out.println("Craps! You lose.");
    }
    else
    {
    int roll;
    // int r = 0;
    // int[] s = new int[5];
    Vector dice = new Vector(5,3);

    do
    {
    die1 = (int)(Math.random()*6 + 1);
    die2 = (int)(Math.random()*6 + 1);
    roll = die1 + die2;
    dice.addElement(new Integer(roll));


    }while(roll != marker && roll != 7);

    System.out.println();

    System.out.println("You diced" + " " + dice.size() + " times");
    System.out.println();
    System.out.println("You rolled as follow :" + dice);

    System.out.println();
    System.out.println("Capacity of Vector is" + " "+ dice.capacity());
    System.out.println();


    if(roll == marker)
    {
    System.out.println("You win!");
    }
    else
    {
    System.out.println("Craps! You lose!");
    }

    }
    }
    }

    The public type Graps must be defined in its own file!

    Dude,
    You trying to create instance of class that don't exits thatsy it showing error.
    Dice dice1 = new Dice();
    Dice dice2 = new Dice();
    There is no Dice class present .....think about it then proceed ????

    It should be like this to get random number.
    import java.util.Random;

    public class tempp
    {

    public int getDice(){
    int a=(int)(Math.random()*6+2);
    return a;
    }
    }
    class Craps
    {
    public static void main(String[] args) {

    tempp t=new tempp();
    int sum,d1,d2;
    d1=t.getDice();
    //d2=t.getDice();
    System.out.println("You rolled "+d1);
    }
    }
