LinkedHashSet Class in Java with Example

LinkedHashSet Class:- Earlier we have discussed HashSet class. In this tutorial we will learn about LinkedHashSet class.

- It is a class which extends HashSet class and implements Set interface.
- Maintains insertion order.
- Contains unique elements

Syntax:

LinkedHashSet <String> hs = new LinkedHashSet <String>();


Sample Program of LinkedHashSet: 

import java.util.LinkedHashSet;

public class LinkedHashSetDemo {

     

      public static void main(String[] args) {

           

            LinkedHashSet <String> hs = new LinkedHashSet <String>();

           

            hs.add("John");

            hs.add("Miller");

            hs.add("Denis");

            hs.add("Javed");

            hs.add("John");

           

            System.out.println("Elements of LinkedHashSet class:" + hs);

      }

}

OutPut: 

Elements of LinkedHashSet class:[John, Miller, Denis, Javed]
