Enums in java compile error -

I am trying to learn Java from below, and I've got this good book to read. Now I have found an example in the book about declaring Enums inside a class, but out of any way I gave it a shot:

  Enum CoffeeSize {BIG, HUGE, OVERWHELMING };  

Spelling it in the book enum and give me this compiled message syntax error, insert ""; To complete blockstations

Are all these important anomes? I mean, should I leave it or is it possible that I use those days?

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

  public class main {enum fu {one, two, three} public static zero chief {string} [] [System.out.println (Foo.One); }}  

You use the keyword enum , not Enum , which is the best of all enum Class is example
