Answer:   The instanceof in Java is also known as type comparison operator because it compares the instance with type. It returns either true or false. If we apply the instanceof operator with any variable that has a null value, it returns false. Consider the following example.
1. class Simple1{
2. public static void main(String args[]){
3. Simple1 s=new Simple1();
4. System.out.println(s instanceof Simple1);//true
5. }
6. }
Test it Now
Output
true
________________________________________
An object of subclass type is also a type of parent class. For example, if Dog extends Animal then object of Dog can be referred by either Dog or Animal class.
