Im trying to get better at programming. so I came up with this game, its like 21 but using dice. Little help would be great, tips, hints, etc thank you

• The first thing that i havent been able to fix is it only rolls 1 die when its supposed to be 2.
  
• Second I have no idea how to do make my counter, i know its supposed to be something like playerTotal++
  
• Third once i get the counter i could make the if statement for it over 21 you lose. then make the comp play.

import java.util.Scanner;

public class AGameOfTwentyOne
{
    public static void main(String [] args)
    {
        String rollDie = "y";
        int playerTotal = 0;
        Scanner kb = new Scanner(System.in);

        Die playerDie = new Die();
        Die compDie = new Die();

        do
        {

            while(rollDie.equalsIgnoreCase("y"))
            {
                System.out.print("Roll the dice? (y/n) : ");
                rollDie = kb.nextLine();
                playerDie.roll();
                playerDie.roll();
                System.out.println("Your score is: "+ playerDie.getValue());

            }

        }while(rollDie == "y");
    }
}

import java.util.Random;

public class Die
{
    private final int SIDES = 6;
    private int value;

    Die()
    {
        roll();
    }

    public void roll()
    {
        Random randomValue = new Random();
        value = randomValue.nextInt(SIDES) + 1;
    }

    public int getValue()
    {
        return value;
    }
}

So for your die roll problem you are not adding to the value, your resting it every time you roll:

value = randomValue.nextInt(SIDES) + 1;

should be

value += randomValue.nextInt(SIDES) + 1;

Second, you can place the playerTotal++ inside the end of your while loop. That will keep track of the number of times you said yes to another roll.

By fixing the code above you will now have a running total that you can check against to see when the player hits a score of 13 or greater. Probably have something inside the last line of the do/while loop.

if( score >= 13 )
{
  print out "You lose"
  break;
}

Wow I cant believe I didnt notice that.

I meant to do the += but I guess I missed it. Always great to have a second pair of eyes. Thanks
