The Java.util.EnumSet.clone() method in Java is used to return a shallow copy of the existing or this set.
Syntax:
Enum_Set_2 = Enum_Set_1.clone()
Parameters: The method does not take any parameters.
Return Value: The method does not return any value.
Below programs illustrate the working of Java.util.EnumSet.clone() method:
Program 1:
// Java program to demonstrate clone() methodimport java.util.*;  // Creating an enum of GFG typeenum GFG {    Welcome,    To,    The,    World,    of,    Geeks};  public class Enum_Set_Demo {      public static void main(String[] args)    {          // Creating an empty EnumSet        // Getting all elements from GFG        EnumSet<GFG> e_set = EnumSet.allOf(GFG.class);        ;          // Displaying the empty EnumSet        System.out.println("Initial set: " + e_set);          // Cloning the set        EnumSet<GFG> final_set = e_set.clone();          // Displaying the final set        System.out.println("The updated set is:" + final_set);    }} |
Output:
Initial set: [Welcome, To, The, World, of, Geeks] The updated set is:[Welcome, To, The, World, of, Geeks]
Program 2:
// Java program to demonstrate clone() methodimport java.util.*;  // Creating an enum of CARS typeenum CARS {    RANGE_ROVER,    MUSTANG,    CAMARO,    AUDI,    BMW};  public class Enum_Set_Demo {      public static void main(String[] args)    {          // Creating an empty EnumSet        // Getting all elements from CARS        EnumSet<CARS> e_set = EnumSet.allOf(CARS.class);        ;          // Displaying the empty EnumSet        System.out.println("Initial set: " + e_set);          // Cloning the set        EnumSet<CARS> final_set = e_set.clone();          // Displaying the final set        System.out.println("The updated set is:" + final_set);    }} |
Output:
Initial set: [RANGE_ROVER, MUSTANG, CAMARO, AUDI, BMW] The updated set is:[RANGE_ROVER, MUSTANG, CAMARO, AUDI, BMW]
