Return Value: The method just returns a copy of the HashSet.
Below program illustrate the Java.util.HashSet.clone() method:
// Java code to illustrate clone()import java.io.*;import java.util.HashSet; public class Hash_Set_Demo { public static void main(String args[]) { // Creating an empty HashSet HashSet<String> set = new HashSet<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 HashSet System.out.println("HashSet: " + set); // Creating a new cloned set HashSet cloned_set = new HashSet(); // Cloning the set using clone() method cloned_set = (HashSet)set.clone(); // Displaying the new Set after Cloning; System.out.println("The new set: " + cloned_set); }} |
Output:
HashSet: [4, Geeks, Welcome, To] The new set: [Geeks, Welcome, To, 4]
