Answer Posted / shubha
Type Casting is conversion of one type data to another type.
Ex:
public class Base{
//Your code goes here
}
public class Derived extends Base
{
//Inherit method or create your own code here
}
public class MainClass {
public static void main(String args[]){
Base b = new Derived(); //reference variable of Base class points object of Derived class
//Derived d = b; compile time error, requires casting
Derived d = (Derived) b; // type casting Base to Derived
//Here you call your base class methods as derived class methods
}
}
