InstanceOfOperatorDemo.java
class InstanceOfOperatorDemo
{
    public static void main(String[] args)
    {
        Parent parentObject = new Parent();
        Parent childObject = new Child();

        System.out.println("parentObject instanceof Parent: "
                + (parentObject instanceof Parent));

        System.out.println("parentObject instanceof Child: "
                + (parentObject instanceof Child));

        System.out.println("parentObject instanceof Employee Interface: "
                + (parentObject instanceof Employee));

        System.out.println();
        
        System.out.println("childObject instanceof Parent: "
                + (childObject instanceof Parent));

        System.out.println("childObject instanceof Child: "
                + (childObject instanceof Child));
        
        System.out.println("childObject instanceof Employee Interface: "
                + (childObject instanceof Employee));


    }

}
Output
parentObject instanceof Parent: true
parentObject instanceof Child: false
parentObject instanceof Employee Interface: true

childObject instanceof Parent: true
childObject instanceof Child: true
childObject instanceof Employee Interface: true
