How to correctly code max, min, and avg in this code?

//I cannot figure out why my code is 1) giving me a null output 2) not calculating the max, min values, and average values. Any help? There are two classes in my code, and I'm supposed to find the average, max, and min of a set of values. -->

this gives me a null output

    for(int index = 0; index < circles.length; index++)
    {            
        System.out.printf("%4s %10.1f %20f", arr[index],

                                             circles[index].getSurfaceArea(),
                                             i++); 
    }
    System.out.println("==============================================================");

I can't get this to print values

    System.out.printf("%20s%n", "Minimum: ", max); 
    System.out.printf("%20s%n", "Maximum: ", min); 
    System.out.printf("%20s%n", "Average: ", circles[4].getAvg()); 
   }
   }
