                   obj.height = 2;

                   obj.length = 10;

                   int y = obj.width * obj.height * obj.length;

                        System.out.println("num1 = " + num1);        

                        System.out.println("num2 = " + num2);         // adding num1 and num2        

                        sum = num1 + num2;        

                        System.out.println("The sum = " + sum);    }}

What is the expected output?

public class Main {
