Dice class for java course

[asmodean]

My instructor wants us to write a dice class that will roll a die, return the value rolled and return a representation of a die face as a String object. Now, none of that is a problem. The problem for me is that she wants this class to do all of that using her pre-written program that has no variables that will hold String data.

Am I missing something? Is there some way to make that program display that String data even though there are only integer variables in the program? We're not allowed to modify her program so I'm lost. Can anyone clue me in? Thanks.

return the value rolled and return a representation of a die face as a String object

That would say that the method must create a String using one of its constructors or that of another class that takes the data type you are using and returns a String.

What should the "representation of a die face" look like?

way to make that program display that String data

Not sure what you are asking here.

You must have code for said program. Can we see it? It would give us a much clearer idea of what you are having trouble with.

i assume the return type of the result of the roll to be int so u can use it toString method

switch (roll)
{
case 1:
{
dieFace = "one\n\n *\n\n\n";
break;
}
case 2:
{
dieFace = "two\n*\n\n *\n\n";
break;
}
case 3:
{
dieFace = "three\n*\n *\n *\n\n";
break;
}
case 4:
{
dieFace = "four\n* *\n\n* *\n\n";
break;
}
case 5:
{
dieFace = "five\n* *\n *\n* *\n\n";
break;
}
case 6:
{
dieFace = "six\n* *\n* *\n* *\n\n";
}
}

but here is the program that she wrote for us to create a class for:

import java.util.Scanner;

public class *********
{
public static void main (String[] args)
{
int rolls, roll1, roll2, numberRolls, sevenRolled = 0;
Scanner input = new Scanner(System.in);

Dice die1 = new Dice();
Dice die2 = new Dice();

System.out.print ("Enter the number of dice rolls: ");
noRolls = input.nextInt();

for (rolls = 1; rolls <= numberRolls; rolls++)
{
System.out.println("Roll #: " + rolls);
roll1 = die1.diceRoll();
roll2 = die2.diceRoll();


if (roll1 == 2 && roll2 == 5 || roll1 == 5 && roll2 == 2 || roll1 == 1 && roll2 == 6 || roll6 == 6 && roll2 == 1 || roll1 == 3 && roll2 == 4 || roll1 == 4 && roll2 == 3)
sevenRolled++;
}

System.out.println ("Number of Dice Rolls: " + numberRolls);
System.out.println ("Number of Times Seven Was Rolled: " + sevenRolled);


}
}


So, this program isn't meant to display die faces. I was just wondering if there was some magical way to make it do something that isn't in the code or if the instructor made a mistake or what.

if (roll1 == 2 && roll2 == 5 || roll1 == 5 && roll2 == 2 || roll1 == 1 && roll2 == 6 || roll6 == 6 && roll2 == 1 || roll1 == 3 && roll2 == 4 || roll1 == 4 && roll2 == 3)

Seems a bit awkward. What if you add roll1 to roll2 and test if the results is == to 7

I've lost what your problem/question is now.

what in the program makes the dice roll AND what format is said dice roll entering the program as e.g. is (dice roll of one coming into your program as an integer or a String) and can we see the tutors original question please.

nothing in the program makes the dice roll, its all done in the class. The roll is returned as an integer. It has to be right? There's nothing to hold string data in the program right?

[Norm]

How are you coming with your problem?

[asmodean]

Well, so far I just wrote methods that did what the instructor asked for, even though the program he wrote for us doesn't use all of them.

I could not tell you from what you have posted only assume you are right.

but anyway a String representation of int one might be o, a String of int two could be oo, etc. use

dieFace = "o"

for example in case 1, thats what it seems the instructor wants but without more information on the question its hard to tell.

I posted the entire program letter for letter the way it was given to me.

dieFace = "o"

for example in case 1, thats what it seems the instructor wants but without more information on the question its hard to tell.

I posted what the instructor wants in the die face representations in the case statement I posted earlier. The same post that has the instructor's program class.
