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]
