although I think it is stretching/breaking the meaning of an enumeration and introducing these constants as enums may make their usage harder rather than simpler actually we could ala:
public enum Language {
EN("en"),
// ...
FR("fr");
private Language(final String l) { language = l;}
public boolean equals(Object o) { return language.equals(o); }
public int hashCode() { return language.hashCode(); }
public String toString() { return language.toString(); }
private final String language;
}
likewise:
public enum MediaType {
public final static String APPLICATION = "APPLICATION";
// ...
APPLICATION_XML(APPLICATION, XML),
// ...
APPLICATION_TEXT(TEXT, PLAIN);
private MediaType(String t, String st) { type = t; subtype = st; }
public boolean equals(Object o) {
// ...
}
public int hashCode() {
// ...
}
public String toString() {
return type + "/" + subtype;
}
public String getType() { return type; }
public String getSubtype() { return subType; }
private final String type;
private final String subtype;
}
the problem I see with that is that if we did not provide a rich enough set of values in the enum a developer would
be forced to extend that set by inheritance ... so maybe just simple string constants will be enough

+1 on the constant reference-safety. I wish there were a way to use enums here. too =(
