Messages in java

I have a challenge:

Imagine you have a set of messages like this:

Code / Message

200567 = A new user was created
462001 = Unknown client number
...

I'm trying to find the neatest, lightest, and easiest to maintain way to use this messages in java.

The rules are:

  1. You need to be able to access the message by its code
  2. You need to be able to print the code
  3. You need to be able to easily change the number of a code in the future

Other notes:

So, anybody has ideas?
(Sorry about my lousy English)

I would put this in an enumeration. 

public enum MessageType {

NEW_USER("String 123", "A new user was created");
private String code, message;

private MessageType(String code, String message) { this.code = code;
this.message = message }

I would go for enumerations because they are to be checked into source control, typically in the environments where I work the properties file is meant to be configured by the individual. Such as an ant build properties file.

Your best bet is probably to have a HashMap<string, string> or HashMap<int, string> that is a static member of your main class or some other relevant class. Write a properties file and a simple method that is called near the start of the program to populate the HashMap.

If I had to implemtn this I would use a HashMap. The code are the keys and the message the values.

Go for Properties File. Use ResourceBundle 

200567 A new user was created
462001 Unknown client number
