Static method, variable parameters

Code:

public class Demo04 {
    public static void main(String[] args) {
        System.out.println(add(1,2,3));
        System.out.println(add(1,2,3,4,5,6,7,8,9));
    }
    // static method 
    public  static  int the Add ( int ... IS) { // variable parameters corresponding to int [] a
        
        int I = 0 ;
        
        for(int i:is){
            sum+=i;
        }
        
        return sum;
    }
}

Within the parameter list can have only one variable parameter, and must be placed at the end
