how non-static enum can be accessed without object?

[Mahesh Murugaiyan]

Hello,

This is Question #3 in practice exam 2 in Bates/Sierra's Practice Exam book.
Numinor is a stand alone class with the "Members" enum. How can this enum(which is a non-static member of Numinor) accessed without creating an object for Numinor class?

public class Fellowship {
	public static void main(String[] args) {

		int h0 = Numinor.Members.HOBBITS.getHeight();
		
		System.out.println(Numinor.check);
		//throws error - Cannot make a static reference to the non-static field Numinor.check

	}

}

class Numinor {

	String check = "Numinor";

	enum Members {
		HOBBITS(48), ELVES(74), DWARVES(50);
		int height;

		Members(int h) {
			height = h;
		}

		int getHeight() {
			return height;
		}
	}
}

But that question is based on the incorrect assertion that the enum is a non-static member of the class in which it's declared. Once you drop that idea, there's no problem at all.

Enums are implicitly static in class.

Thanks Ninad. Thanks Paul, yes, thats makes total sense. Other than enum, interface(constants) are there any other entitiy that is implicitly static ? I will add this to my study notes.
