What is type casting. Explain it with reference to classes...

Answer / kiran vaidya

Type casting means converting some type to some another
type.

for example, there are three classes:

class Employee
{
//Logic for this class

}

class Manager:Employee
{
//Logic for this class

}

class Clerk:Employee
{
//Logic for this class

}

class Program
{
static void Main(string [] args)
{
Employee e=new Employee();

//Type casting
Manager m=(Manager)e;

//Or
Clerk c=(Clerk)e;

}

}

Answer / 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
}
}
