Java > Array-1 > sum3 (CodingBat Solution)

Problem:

Given an array of ints length 3, return the sum of all the elements.

sum3({1, 2, 3}) → 6
sum3({5, 11, 2}) → 18
sum3({7, 0, 0}) → 7


Solution:

public int sum3(int[] nums) {
  return nums[0] + nums[1] + nums[2];
}

    public int sum3(int[] nums) {
    int sum=0;
    for(int i=0;i<nums.length;i++)
    {
    sum = sum + nums[i];

    }

    return sum;

    }

    public int sum3(int[] nums) {
    int total = 0;

    for(int x : nums){
    total = total + x;
