EnumSet clone() Method in Java

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

// 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

// 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]
