    Default array trouble

    I'm trying to populate an array with numbers 1-10 of size 100 and then finding the average of the array and i can't seem to figure out where i'm going wrong. (the multiple methods are required...also i'm not too sure how to correctly use multiple methods. possibly where i'm going wrong.)
    import java.util.Random;
     
    public class wtf 
    {
     
        public static void main(String[] args)
        {
     
          int [] values = new int [100];
           populateArray(values);
     
     
     
     
        }
        public static void populateArray (int []values )
        {
            Random generator = new Random();
            for (int z = 0; z < values.length; z++)
            {
            values[z] = generator.nextInt(10) + 1;
     
     
            }
          average (values);
     
     
        }
     
     
     
        public static void average (int values [] )
        {
    	int sum = 0;
           for (int r = 0; r < values.length; r++)
           {
     
               sum = sum + values [r];
    	   sum = sum/values.length;
     
           }
    	 System.out.println ("The average is " + sum);
     
        }
    }

    }
