How to calculate average in Java?

To calculate average in Java, first sum the numbers in a for loop, then divide by amount of numbers.

Here's how you do it:

double[] numbers = new double[] { 1.0, 5.0, 12.6 };
double sum = 0.0;

for (int i = 0; i < numbers.length; i++) {
  sum += numbers[i];
}

double average = sum / numbers.length;

// 6.2
System.out.println(average);
