Submitted by Nidhi, on May 28, 2022

Problem Solution:

In this program, we will create an Enum for COLORS constants. Then we will create an EnumSet collection using the range() method from an enum.

Program/Source Code:

The source code to create an EnumSet using the range() method is given below. The given program is compiled and executed successfully.

// Java program to create an EnumSet 
// using range() method

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;

    enumSet = EnumSet.range(COLORS.GREEN, COLORS.BLACK);

    System.out.println("EnumSet is: " + enumSet);
  }
}

Output:

EnumSet is: [GREEN, BLUE, BLACK]

Explanation:

The Main class contains a main() method. The main() method is the entry point for the program. And, created a reference of the EnumSet collection and initialized it with elements of COLORS elements using the range() method and printed the result.
