Below program illustrate the Java.util.LinkedHashSet.clone() method:




// Java code to illustrate clone()
import java.io.*;
import java.util.LinkedHashSet;
  
public class Hash_Set_Demo {
    public static void main(String args[])
    {
        // Creating an empty LinkedHashSet
        LinkedHashSet<String> set = new LinkedHashSet<String>();
  
        // Use add() method to add elements into the Set
        set.add("Welcome");
        set.add("To");
        set.add("Geeks");
        set.add("4");
        set.add("Geeks");
  
        // Displaying the LinkedHashSet
        System.out.println("LinkedHashSet: " + set);
  
        // Creating a new cloned set
        LinkedHashSet cloned_set = new LinkedHashSet();
  
        // Cloning the set using clone() method
        cloned_set = (LinkedHashSet)set.clone();
  
        // Displaying the new Set after Cloning;
        System.out.println("The new set: " + cloned_set);
