Given an array of ints, return the sum of the first 2 elements in the array. If the array length is less than 2, just sum up the elements that exist, returning 0 if the array is length 0.

Example: sum2({1, 2, 3}) → 3
sum2({1, 1}) → 2
sum2({1, 1, 1, 1}) → 2

public int sum2(int[] nums) {


return nums[0] + nums[nums.length-1]
int value = 0;
for (int x = 0; x<nums.length-1; x++]{
value = value + nums[x]
}
return value;
}

}

I really don't see a problem here, just return nums[0] + nums[1];

And maybe you should check if the array contains at least two elements before that.

Is that what you were looking for?
