Question

                                                                                                                                                                                                                                                                                   

Write a static method named sumOf that takes an array of int values as an argument (you may safely assume that the array contains at least 1 element). This method should return the sum of all values in the array.

Examples:
    Given the following array declaration and definition.
        int[] theArray = {0, 0, 0, 0, 0, 0};
        sumOf(theArray) will return 0

    Given the following array declaration and definition.
        int[] theArray = {1, 1, 1, 1, 1, 1};
        sumOf(theArray) will return 6

    Given the following array declaration and definition.
        int[] theArray = {1, 3, 5, 6, 4, 2};
        sumOf(theArray) will return 21

Answer 1

Code:

class XYZ
{   // function you need
    public static int sumOf(int ar[])
    {
        int sum = 0;
        for(int i=0;i<ar.length;i++)
        {
            sum += ar[i];
        }
        return sum;
    }
    public static void main(String args[])
    {
        int[] theArray = {1,3,5,6,4,2};
        System.out.println(sumOf(theArray));
        
    }
}

Output:
