Java method to sum any number of ints

Question

I need to write a java method sumAll() which takes any number of integers and returns their sum.

sumAll(1,2,3) returns 6
sumAll() returns 0
sum         


        

Answer 1

You could do, assuming you have an array with value and array length: arrayVal[i], arrayLength:

int sum = 0;
for (int i = 0; i < arrayLength; i++) {
    sum += arrayVal[i];
}

System.out.println("the sum is" + sum);

I hope this helps.
