EnumSet clone() Method in Java

Last Updated : 02 Jul, 2018

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() method 
import java.util.*; 
  
// Creating an enum of GFG type 
enum 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() method 
import java.util.*; 
  
// Creating an enum of CARS type 
enum 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]
