Testing for division by zero

Question

This program consists of 2 classes.
The getRating method performs actual calculations based on the below values. The program runs OK, until you test it when dividing by zero.
I am trying to return 0 if there is division by zero. I don't think I am approaching this correctly. In all 4 calculations, the only variable that the other numbers are divided by is attempts.
So, I was trying to catch the value of attempts here, then return a 0 if attempts are <= 0.
Is this the correct location to put the conditional logic? Should it be up in the method that actually performs the calculations?
The compile error indicates "cannot find symbol" at the if(r2... test.
Thanks
  System.out.println("\nTest2");
    Quarterback r2 = new Quarterback("Fred Savage", "Loyola");
    r2.setYards(78);
    r2.setTouchdowns(0);
    r2.setCompletions(5);
    r2.setAttempts(0);
    r2.setInterceptions(2);
    if(r2.setAttempts>0){
     System.out.println("The rating should be 36.7.");
     System.out.println("Your code calculates a rating of " + r2.getRating());
    } else {
     System.out.println("Attempts were zero so rating is zero" + "0");
    }

Answer 1

if(r2.setAttempts>0){This isn't valid syntax. setAttempts is a method which takes parameters, for one thing, and likely doesn't return a value that you can compare with anything. There might be a getAttempts() method for that, but it's your class so supposedly only you know about that.
But it sounds like you just don't want the getRating() method to fail with a division by zero error. Well, put the logic in that method, not here.
So in the getRating method, you should check for the attempts value being zero before you try to divide by it.
