Question 43

Essay

class InstanceofDemo
{
    public static void main(String[] args)
   {
        Parent object1 = new Parent();
        Parent object2 = new Child();
        System.out.println("object1 instanceof Parent: "
            + (obj1 instanceof Parent));
        System.out.println("object1 instanceof Child: "
            + (obj1 instanceof Child));
        System.out.println("object1 instanceof MyInterface: "
            + (obj1 instanceof MyInterface));
        System.out.println("object2 instanceof Parent: "
            + (obj2 instanceof Parent));
        System.out.println("object2 instanceof Child: "
            + (obj2 instanceof Child));
        System.out.println("object2 instanceof MyInterface: "
            + (obj2 instanceof MyInterface));
     }
}
