instanceof Operator |
instanceof
operator
The instanceof
operator allows you to check the validity of a IS A
relationship. If at any point of time, we are not sure about this and we want to validate this at runtime, we can do the following:
//assuming vehicle is an instance of Class `Car` the expression inside the 'if' will return true
if(vehicle instanceof Car){
//do something if vehicle is a Car
}
Note: If you apply the instanceof operator with any variable that has null value, it returns false.
