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 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]
