Here, try this for a trowing-routine (for one die):
Code:
        double throw = Math.random();
        dice1 = (int) Math.ceil((throw*(MAXIMUMEYES-MINIMUMEYES+1)+(MINIMUMEYES-1)));
Where MAXIMUM and MINIMUM are the maximum and minimum number of eyes on the die, respectivly. For a normal die, these would be 6 and 1.

If you feel up to it, you could even create a seperate die-class. In your program, you would create two instances of the class. The class could look something like this:

Code:
import java.lang.Math;

public class Die
{
    private static final int MINIMUMEYES = 1; // minimum number of eyes on the die
    private static final int MAXIMUMEYES = 6; // maximum number of eyes on the die
    
    private int eyes;  // Represents number of eyes trown
   
    public int getEyes()
    // value:  eyes
    {
        return eyes;
    }

    public void roll()
    // action: roll the die, and set any value out of {1,2,3,4,5,6} in eyes
    {
        double throw1 = Math.random();
        eyes = (int) Math.ceil((throw1*(MAXIMUMEYES-MINIMUMEYES+1)+(MINIMUMEYES-1)));
    }
}
