classes and creating objects

[Latanyar]

Create a Dice class that has a face data field (that indicates the current value showing). The class should have a getFace method which returns the current value of face, and a roll method that chooses a random value for face. Write a main program that creates 2 Dice objects. The main program should roll both dice and display the value showing for each. Be sure to use proper style. Create a jar file of your program and attach to this assignment page.

This is what I have:

public class Dice
{
int face = 6;


// returns the current value of face
 int getFace()
 {
     return face;
 }
 
 
 int roll()
 {
    return 1 + (int)(Math.random() * 7); 
 }
 

}

public class diceGame
{
    public static void main(String[] args)
    {
        Dice dice1 = new Dice();
        
        System.out.println("dice1 is " + dice1.getFace());
        
        
        Dice dice2 = new Dice();
        
        System.out.println("dice2 is " + dice2.roll());
    }
}

Is this correct?

No, it's not correct. The roll() method should change face and that's it. It shouldn't return an int. Rather the result of the roll is obtained by calling getFace(). And your formula for rolling is not right as it will allow a result of 7 (check it and see).

Also, you will want to test your code to find out best if it works or not.

<pedant>...and it's Die not Dice in the singular...</pedant>

Could you give me an example, because I am really confused about this. I changed the math.random to 6.

The instructions pretty much spell out what's needed. Let's see your latest code.
