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));
     }
}
The above code defines a parent class (named Parent ), a simple interface (named MyInterface ), and a child class (named Child ) that inherits from the parent and implements the interface.
Following program execution, what will be the output of the six println statements?
