A simple program of VarArgs!

package com.company;

public class varages {
    static int sum(int a,int b){
        return a+b;
    }
    public static void main(String[] args) {
        System.out.println("The sum of 4 and 5 is: "+ sum(4,5));
    }
}Output: The sum of 4 and 5 is: 9

Taking 2 methods!

package com.company;

public class varages {
    static int sum(int a,int b){
        return a+b;
    }
    static int sum(int a,int b, int c){
        return a+b+c;
    }
    public static void main(String[] args) {
        System.out.println("The sum of 4 and 5 is: "+ sum(4,5));
        System.out.println("The sum of 4, 5 and 6 is: "+ sum(4,5, 6));    }
}Output: The sum of 4 and 5 is: 9
        The sum of 4, 5 and 6 is: 15

Using varArgs to access the method

static int sum(int...arr){
        int result=0;                  
        for (int a: arr){
            result +=a; 
        }
        return result;     //by this way we can create ultimate results
    }
    public static void main(String[] args) {
        System.out.println("The sum of 4 and 5 is: "+ sum(4,5));
        System.out.println("The sum of 4, 5 and 6 is: "+ sum(4,5, 6));
        System.out.println("The sum of 4,5,6 and 9 is: "+ sum(4,5,6,9));
    }
}Output: The sum of 4 and 5 is: 9
        The sum of 4, 5 and 6 is: 15
        The sum of 4,5,6 and 9 is: 24
