Problem Solution:

In this program, we will create an Enum for COLORS constants. Then we will create an EnumSet collection and add elements using add() method.

Program/Source Code:

The source code to add elements to the EnumSet collection using add() method is given below. The given program is compiled and executed successfully.

// Java program to add elements to EnumSet 
// using add() 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.noneOf(COLORS.class);

    enumSet.add(COLORS.RED);
    enumSet.add(COLORS.GREEN);
    enumSet.add(COLORS.BLUE);

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

Output:

enumSet elements: [RED, GREEN, BLUE]
