Answer to my own question: public class EnumTest { public enum Weekday { SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY } public static void main(String[] args) { System.out.println(Weekday.SUNDAY); } } This produces "SUNDAY" as output. The EnumTest.Weekday "class" doesn't override the toString method, allowing java.lang.Enum (it's superclass) to handle that. java.lang.Enum.toString is implemented like this: public String toString() { return name; } ... and "name" is a String which is initialized in the constructor (when I decompile EnumTest.Weekday, I can see it uses the string "Sunday", as one might expect). So I'm surprised that Oliver is getting that weird output. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAky3Wn4ACgkQ9CaO5/Lv0PB1yACeKEbeavY+ois6H2BMndqRLWsm CxEAn0SsiuLsvv6O/Szd3QKsPZ66Mxgj =bQGI -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
