import java.util.Iterator;
import java.util.LinkedHashSet;
import java.util.Set;

public class LinkedHashSetExample{
    public static void main(String [] args){
         Set ht = new LinkedHashSet();
        Iterator it = ht.iterator();
           while (it.hasNext()) {
      System.out.println("Size :" + ht.size());



Size :4

Description:- The above example demonstrates you the Set interface. Since Set is an interface, you need to instantiate a concrete implementation of the interface in order to use it. Here Set is implemented by its subclass LinkedHashSet. LinkedHashSet does not accept duplicate values. So here we have check whether the added elements are duplicate or not Then we have removed an element ??R?? using remove() method from the LinkedHashSet and iterated the remaining elements of LinkedHashSet r using Iterator and display them.
