The Java.util.HashSet.clone() method is used to return a shallow copy of the mentioned hash set. It just creates a copy of the set.
Syntax:
Hash_Set.clone()
Parameters: The method does not take any parameters.
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]
