package Practice;

import java.security.KeyStore;

import java.util.*;

public class LinkedHashMapExample {

    public static void main(String[] args)

    {

        LinkedHashMap l=new LinkedHashMap();

        l.put(null,null);

        l.put(null,null);//it takes only one null key

        l.put(1,"ravi");

        l.put(2,"kumar");

        l.put(3,"sagar");

        l.put(4,"Om");

        l.remove(4);

        System.out.print(l);

        System.out.println(l.get(2));

        l.clear();

        System.out.println(l.values());

        System.out.println(l.keySet());

        Map map =new LinkedHashMap();

        Home home=new Home("Ravi",23,25000,"Delhi");

        Home home1=new Home("Ritu",24,21000,"Goa");

        Home home2=new Home("Om",28,22000,"Mumbai");

        Home home3=new Home("Sweta",28,24000,"Chennai");

        map.put(1,home);

        map.put(2,home1);

        map.put(3,home2);

        map.put(4,home3);

        System.out.println(map.get(4));

    }

}

class Home{

    public String name;

    int age;

    public String address;

    int income;

    public Home(String name, int age,int income,String address){

        this.name=name;

        this.age=age;
