JAVA program to handle same function with different number of parameters

In this post i would like show you a cool feature of java to handle functions with different parameter sets. For example if you want to find sum of a set of parameters which maybe 2or 3or400 you can use this feature instead of doing messy convertions to array.

public class threeDots{



    static void sumIt(int...x){

        int t=0;

        for(int i:x)

            t+=i;

        System.out.println(t);

    }



    public static void main(String[] args) {

        sumIt(1);

        sumIt(1,2);

        sumIt(1,2,3);

        sumIt(1,2,3,4);

        sumIt(1,2,3,4,5);

        sumIt(1,2,3,4,5,6);        

    }

}

Output:
1
3
6
10
15
21
