import java.util.Scanner;

class additionOfNumbers {
  public static void main(String args[]) {
    int number01, number02, sum;
    
    System.out.println("Enter Two Integer Numbers");
    System.out.println("__________________________");
    
    Scanner in = new Scanner(System.in);
    System.out.print("nEnter First Number: ");
    number01 = in.nextInt();
    System.out.print("nEnter Second Number: ");
    number02 = in.nextInt();
    System.out.println("nnInput NumbersnFirst Number = " + number01 + "nSecond Number = " + number02);
    
    sum = number01 + number02;
    
    System.out.println("nAddition Of "+ number01+" and " + number02 +" is : " + sum);
  
  }
}
