Question

I have a question about the following code:

public Class Settings{
 public static final String WelcomeMessage= "helloworld";
 public static final String ByeMessage= "yo";

public static String[] widgets = {WelcomeMessage,ByeMessage};

}

The compiler complains about duplicat variables. Can I delete the 2 separate variables and still acces WelcomeMessage by Settings.WelcomeMessage? I don’t need to acces it by Settings.widget[0]? And is it possible to add another variable to the WelcomeMessage variable (by for instance using a static hashtable)?

Edit: I know this code doesn’t look right but it’s just an example because I wondered why the compiler thinks WelcomeMessage (as a separata variable) is the same as the variable in the Widgets array.

Answer 1

I would consider java-enums in your case:

public enum Settings {
    WelcomeMessage ("helloworld"),
    ByeMessage   ("yo");

    public final String value;

    Settings(String value) {
        this.value = value;
    }
}

You can access now the values via Settings.WelcomeMessage.value. Also you get a List of the enums with Settings.values().
