Question

Write a class named DiceGame.java that contains a method called diceSum that prompts the use for a desired sum, then repeatedly simulates the rolling of 2 six-sided dice until their sum is the desired sum (use a do/while loop). Here is a sample dialogue with the user:
Desired dice sum: 9
4 and 3 = 7
3 and 5 = 8
5 and 6 = 11
5 and 6 = 11
1 and 5 = 6
6 and 3 = 9
You must perform checks to make sure the user enters an integer between 2 and 12 and reprompt if not. You must also reprompt for non-int values. Your code should include assertion comments for assertions that are always true (provable).

{

    public static void main(String[] args)

    {

        // create object to get user input

        Scanner sc = new Scanner(System.in);

       

        int sum;

       

        // infinite loop

        while(true)

        {

            System.out.println("Desired dice sum:");

           

            // get user input

            sum = sc.nextInt();

           

            // if the entered sum is not correct

            if( sum >= 2 && sum <= 12 )

                break;

           

            System.out.println("Entered value is not correct.\n");

        }

       

        int x, y;

       

        // loop untill the sum is not equal to sum

        do{

            // generate random number in range 1 - 6

            x = 1 + (int)(Math.random() * ((6 - 1) + 1));

           

            // generate random number in range 1 - 6

            y = 1 + (int)(Math.random() * ((6 - 1) + 1));

           

            System.out.println(x + " and " + y + " = " + (x + y));

        }

        while( x + y != sum );

    }

}
