Hi Thomas, Welcome to JavaRanch! There are some things, like the "length" pseudo-instance-variable in arrays, or the "class" pseudo-static-variable, or the "this" member, or the "super()" method, that are more part of the language than part of the API, and this is one of them. The primary source for stuff like this is the Java Language Specification, browseable free online in ... |
Hi all, I have a question about Java 5 enums. I'm trying to have UserState.ACTIVE in my code but have "A" saved to the database. Then when I get "A" from the database I get the enum representing UserState.ACTIVE. We're limited by the User POJO which can't change from using a String. Here's my code so far... public enum UserState { ... |
So I've set up some enums in my POJO, and I'm using them in the output. For example, I have the following. public enum Breeds {Setter, Terrier, Lab} System.out.println("The dog breed is "+Breeds.Setter.toString()); It's against convention, but it works. However, I've run into the problem with using enums with spaces. For example, how do I handle "Great Dane"? I can't put ... |

I know I could do an "if" statement. However, this is a contrived example with only a few enum values. In the real world, this enum list could be quite large. I have looked into reflection, but I don't know whether there is an easier way to achieve my objective? Thank you for your time, Harold Clements |
I haven't worked with Enums in awhile, but I was wondering if it can skip values. For instance, I am implementing a spec that has error codes in it that for some reason skip some values. They go 1,2,3,4,5,6,8,10,11 skipping 7 and 9 I'd like to make an enum for these constants, but I don;t think this is possible. I can ... |

I dont think it was implict kablair. Especially when this was written at the link posted above [quote] The new enum declaration defines a full-fledged class (dubbed an enum type).
