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 need:

public int sumAll(int...numbers){

    int result = 0;
    for(int i = 0 ; i < numbers.length; i++) {
        result += numbers[i];
    } 
    return result;
}

Then call the method and give it as many int values as you need:

int result = sumAll(1,4,6,3,5,393,4,5);//.....
System.out.println(result);
