Java Upcasting

When reference variable of a parent class refers to an object of child class then we call it upcasting.

Example is below.


Class Bank(){
}

Class ComBank extends Bank(){
}

Class BankModule(){
public static void main(String args[]){
Bank bank = new ComBank(); // This is the process of upcasting
}
}
