Inheritance

 Inheritance- Inheritance is the Reusability of class. 

Inheritance defines the usabilty of class members in another class. 

Inheritance Working Methodology- 

Class Sharing.

Types of Class- 

1. Base Class.

2. Derived Class.

Rules for inheritance- 

1. Always the last class object is created. 

2. main class can not be counted in no. of classes, it's a driver class.

3. All base class members can be accessed in derived class but not the vice versa. 

Example-  

import java.util.Scanner;

class First

{

   public void display()

{

    System.out.println("This is base class");

}

} 

class Second extends First

{

   public void show()

{

System.out.println("This is derived class");

}

}

public class inheri 

{// driver class [class body]

  

 public static void main(String args[]) 

  {// main body

           

        Second s1 = new Second();

        s1.display();      

        s1.show();

   }  

}
