Write a program for multilevel inheritance such that country is inherited from continent. State is inherited from country. Display the place, state, country and continent.

 

import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.IOException;
class Continent
{
String con;
InputStreamReader i = new InputStreamReader(System.in);
BufferedReader r = new BufferedReader(i);
void con_input() throws IOException
{
System.out.println("Enter Continent Name: ");
con = r.readLine();
}
}
class Country extends Continent
{
String cou ;
void cou_input() throws IOException
{
System.out.println("Enter Country Name: ");
cou = r.readLine();
}
}
class State extends Country
{
String sta;
void sta_input() throws IOException
{
System.out.println("Enter State Name: ");
sta = r.readLine();
}
}
class Main extends State
{
String pla;
void pla_input()throws IOException
{
System.out.println("Enter Place Name : ");
pla = r.readLine();

}

public static void main( String argsp[] )throws IOException
{
Main s = new Main();
s.con_input();
s.cou_input();
s.sta_input();
s.pla_input();
System.out.println("\n\nContinent: "+s.con);
System.out.println("Country: "+s.cou);
System.out.println("State: "+s.sta);
System.out.println("Place :" + s.pla);
}
}

Output:

Enter Continent Name:
Asia
Enter Country Name:
India
Enter State Name:
Maharashtra
Enter Place Name :
Pune

Continent: Asia
Country: India
State: Maharashtra
Place :Pune
