Class getEnumConstants() method in Java with Examples

Last Updated : 12 Jul, 2025

The getEnumConstants() method of java.lang.Class class is used to get the Enum constants of this class. The method returns the Enum constants of this class in the form of an array of objects comprising the enum class represented by this class. Syntax:

public T[] getEnumConstants()

Parameter: This method does not accepts any parameter Return Value: This method returns the specified Enum constants of this class in the form of an array of Enum objects. Below programs demonstrate the getEnumConstants() method. Example 1:

Java

// Java program to demonstrate
// getEnumConstants() method

import java.util.*;

enum A {}

public class Test {

    public Object obj;

    public static void main(String[] args)
    {

        // returns the Class object for this class
        Class myClass = A.class;

        System.out.println("Class represented by myClass: "
                           + myClass.toString());

        // Get the Enum constants of myClass
        // using getEnumConstants() method
        System.out.println(
            "Enum constants of myClass: "
            + Arrays.toString(
                  myClass.getEnumConstants()));
    }
}

Output:

Class represented by myClass: class A
Enum constants of myClass: []

Example 2:

Java

// Java program to demonstrate
// getEnumConstants() method

import java.util.*;

enum A {
    RED,
    GREEN,
    BLUE;
}

class Main {

    private Object obj;

    public static void main(String[] args)
    {

        try {

            // returns the Class object for this class
            Class myClass = A.class;

            System.out.println("Class represented by myClass: "
                               + myClass.toString());

            // Get the Enum constants of myClass
            // using getEnumConstants() method
            System.out.println(
                "Enum constants of myClass: "
                + Arrays.toString(
                      myClass.getEnumConstants()));
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

Class represented by myClass: class A
Enum constants of myClass: [RED, GREEN, BLUE]
