Question

I’m trying to learn java from bottom up, and I got this great book to read http://www.amazon.com/o/ASIN/0071591060/ca0cc-20 . Now I found example in the book about declaring Enums inside a class but outside any methods so I gave it a shot :

Enum CoffeeSize { BIG, HUGE, OVERWHELMING }; 

In the book its spelled enum and I get this compile message Syntax error, insert ";" to complete BlockStatements

Are the Enums that important at all?I mean should I skip it or its possible that I will be using those some day?

Answer 1

This is the correct way to declare an enum inside a class:

public class Main {
  enum Foo { One, Two, Three }

  public static void main(String args[]) {
    System.out.println(Foo.One);
  }
}

You use the enum keyword, not Enum, which is the superclass of all enum instances.
