Okay so for university, we have to Create two Die objects and roll them several times, counting the number of snake eyes that occur.
this is the code I have, I need some help as every time I compile and execute my program, I get a fail on it. I'm not 100% sure where i'm going wrong, and I Don't know entirely whether solutions will help unless you went to my university, but any help is appreciated :) Thanks.

(This is all coded in JPLIDE)
final int ROLLS = 500;
int num1, num2, count = 0;
Die die1 = new Die();
Die die2 = new Die();
for (int roll=1; roll <= ROLLS; roll++)
{num1 = 1;
num2 = 1;
if (num1 == 1 && num2 == 1) // check for snake eyes
count++;
}
System.out.println ("Number of rolls: " + ROLLS);
System.out.println ("Number of snake eyes: " + count);
System.out.println ("Ratio: " + (float)count / ROLLS);
}}}
class Die
{private final int MAX = 6; // maximum face value
private int faceValue; // current value showing on the die
//-----------------------------------------------------------------
// Constructor: Sets the initial face value of this die.
//-----------------------------------------------------------------
public Die()
{faceValue = 1;
}
//-----------------------------------------------------------------
// Computes a new face value for this die and returns the result.
//-----------------------------------------------------------------
public int roll()
{faceValue = (int)(Math.random() * MAX) + 1;
return faceValue;
}
//-----------------------------------------------------------------
// Face value mutator. The face value is not modified if the
// specified value is not valid.
//-----------------------------------------------------------------
public void setFaceValue (int value)
{if (value > 0 && value <= MAX)
faceValue = value;
}
//-----------------------------------------------------------------
// Face value accessor.
//-----------------------------------------------------------------
public int getFaceValue()
{return faceValue;
}
//-----------------------------------------------------------------
// Returns a string representation of this die.
//-----------------------------------------------------------------
public String toString()
{String result = Integer.toString(faceValue);
return result;
}
}
This looks wrong. You set
num1 = 1
andnum2 = 1
and then check if both are equal to 1.. of course they are going to be equal to 1. I assume you meant to do something likenum1 = die1.roll()
num2 = die2.roll()
This will at least make it so that you don't have snake eyes all 500 times.
