Return Value: This method returns true if this Class is the Enum class. It returns false otherwise.
Below programs demonstrate the isEnum() method.
Example 1:
 

Java




// Java program to demonstrate isEnum() method
 
public class Test {
    public static void main(String[] args)
        throws ClassNotFoundException
    {
 
        // returns the Class object for this class
        Class myClass = Class.forName("Test");
 
        System.out.println("Class represented by myClass: "
                           + myClass.toString());
 
        // Check if this class is an enum
        // using isEnum() method
        System.out.println("Is Test an enum: "
                           + myClass.isEnum());
    }
}

Output:

Is Test an enum: false

 

Example 2:
 

Java




// Java program to demonstrate isEnum() method
 
enum A {}
 
public class Test {
 
    public static void main(String[] args)
        throws ClassNotFoundException
    {
 
        // returns the Class object for A
        Class myClass = A.class;
 
        // Check if myClass is an enum
        // using isEnum() method
        System.out.println("Is A an enum: "
                           + myClass.isEnum());
    }
