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

public static int sumOf(int[] nums) {

    int sumTotal = 0;
    // loop through the array, pick the number and add it to sumTotal
    for (int index = 0; index < nums.length; index++) {
        sumTotal += nums[index];
    }
    // return the total sum
    return sumTotal;
}
