Java example to create an EnumSet collection.
Submitted by Nidhi, on May 27, 2022
Problem Solution:
In this program, we will create an Enum for COLORS constants. Then we will create a set of enum constants using the EnumSet collection.
Program/Source Code:
The source code to create an EnumSet collection is given below. The given program is compiled and executed successfully.
// Java program to create an EnumSet collection
import java.util.*;
//Enum for color constants
enum COLORS {
RED,
GREEN,
BLUE,
BLACK,
WHITE
};
public class Main {
public static void main(String[] args) {
EnumSet < COLORS > enumSet;
//Adding elements to EnumSet.
enumSet = EnumSet.of(COLORS.BLUE, COLORS.BLACK, COLORS.GREEN, COLORS.WHITE);
System.out.println("EnumSet is: " + enumSet);
}
}
Output:
EnumSet is: [GREEN, BLUE, BLACK, WHITE]
Explanation:
The Main class contains a main() method. The main() method is the entry point for the program. And, created a reference of EnumSet collection and initialized it with of() method with constants of the enum. After that, we printed the created enum.
