IMPLEMENTATION OF POLYMORPHISM [ java ]

IMPLEMENTATION  OF  POLYMORPHISM

AIM:

            To write a java program to implement polymorphism by creating vehicle class hierarchy using inheritance.

           

ALGORITHM:

            1 .Create the class vehicle .Declare its variables and define its functions.

            2. Create new class car from the base class vehicle and declare its functions

            3. Create bike class from the base class vehicle and using constructor give details about                     the vehicle and display the result.

            4. In the main function create objects for classes and call the corresponding function and                display the result.

PROGRAM:

import.java.io.*;

 class vehicle

{

    String name,model,color;

            void getdata()throws IOException

            {

                       

                        DataInputStream dis=new DataInputStream(System.in);

                        System.out.println("Enter the  name:");

                        name=dis.readLine();

                        System.out.println("Enter the  model");

                        model=dis.readLine();

                        System.out.println("Enter the color");

                        color=dis.readLine();

            }

                        void putdata()

                        {

                        System.out.println("Carno=" +name);

                        System.out.println("Carmodel="+model);

                        System.out.println("Carcolor="+color);

                        }         

}

class car extends vehicle

{

            String name1,model1,color1;

            void getdata()throws IOException

            {

                        System.out.println("\nEnter the car details");

                        DataInputStream dis=new DataInputStream(System.in);

                        System.out.println("Enter the car name:");

                        name1=dis.readLine();

                        System.out.println("Enter the car model");

                        model1=dis.readLine();

                System.out.println("Enter the car color");

                        color1=dis.readLine();

            }

                        void putdata()

                        {

                        System.out.println("Carnname=" +name1);

                        System.out.println("Carmodel="+model1);

                        System.out.println("Carcolor="+color1);

                        }         

}

class bike extends vehicle

{  

    String name2,model2,color2;

            void getdata()throws IOException

            {

                        System.out.println("Enter the bike details");

                        DataInputStream dis=new DataInputStream(System.in);

                        System.out.println("Enter the bike name:");

                        name2=dis.readLine();

                        System.out.println("Enter the bike model:");

                        model2=dis.readLine();

                        System.out.println("Enter the bike color:");

                        color2=dis.readLine();

            }

                        void putdata()

                        {

                        System.out.println("bikename=" +name2);

                        System.out.println("bikemodel="+model2);

                        System.out.println("bikecolor="+color2);

                        }         

}

class vehicle2

{

            public static void main(String args[])throws IOException

            {

               vehicle v=new vehicle();

                bike b=new bike();

                v=b;

                v.getdata();

                v.putdata();

                car c=new car();

                v=c;

                v.getdata();

                v.putdata();

            }

}

OUTPUT:

Enter the bike details

Enter the bike name:

pulsar

Enter the bike model:

CTS125

Enter the bike color:

red

bikename=pulsar

bikemodel=CTS125

bikecolor=red

Enter the car details

Enter the car name:

Logan

Enter the car model

Lg100

Enter the car color

silver

Carnname=Logan

Carmodel=Lg100

Carcolor=silver

RESULT
            Thus the vehicle class hierarchy using inheritance was implemented.
