Explain about instanceof operator in java

Comment

An instanceof in Java is a comparison operator which, given an object instance, 
checks whether that instance is of a specified type (class/sub-class/interface) 
or not. Just like other comparison operators, it returns true or false.

Comparing any object instance with a null type through instanceof operator 
returns a false.
  
Instanceof operator is used to test the object is of which type.

Syntax : <reference expression> instanceof <destination type>
Instanceof returns true if reference expression is subtype of destination type.
Instanceof returns false if reference expression is null.
