//creating a default constructor  
 Add() {
  Scanner sc = new Scanner(System.in);
  
  System.out.print("Enter two numbers:");
  int a = sc.nextInt();
  int b = sc.nextInt();
  
  sum = a+b;
 }
//method to display the values  
 void display() {
  System.out.print("Sum is:"+sum);
 }
 public static void main(String args[]) {
