Enum values().length vs private field

Question

I have enumeration like this:

public enum Configuration {
    XML(1),
    XSLT(10),
    TXT(100),
    HTML(2),
    DB(20);

    private final int id;
    pri         


        

Answer 1

By storing the count you're violating the DRY principle, so unless you have a very good reason, you shouldn't.
