The following program defines an array of four integers, wires in integers via an array initializer, computes the sum of the integers, and displays the average:

public class Demonstrate { 
 public static void main (String argv[]) { 
  int sum = 0; 
  int durations [] = {65, 87, 72, 75}; 
  for (int counter = 0; counter < durations.length; ++counter) { 
    sum = sum + durations[counter]; 
  } 
  System.out.print("The average of the " + durations.length); 
  System.out.println(" durations is " + sum / durations.length); 
 } 
} 
--- Result --- 
The average of the 4 durations is 74
