Passing Arrays using Methods

Introduction

Now you can do many different functions using an array. For example you can cacluate the average of an array, and print an array. Now let's look at how you could write a method to perform thoses tasks. Usuallly such methods will accept an array as an arguement.

For example, the previous chapter showed you how to use a for loop to sum the contents of an array:

public class SumArray
{
    public static void main (String args[]){
        int[] numbers = {1,2,3,4,5,6};
        int sum = 0;

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

Now, let's imagine that you want to write a method
