The JLS does not (presumably) define immutable for the same reason it does not define singleton or aardvark or any other implementation vehicle. If there were an immutable modifier in the same way that there is final modifier then it would be a feature of the language but there isn't so it's not. Mutability is an implementation concept in the same way that deque is an implementation concept. the final modifier can be useful when implementing an immutable component but final and immutable are not the same thing at all. A final *variable* is immutable but an immutable component is not necessarily final. There's a brief discussion of immutability here http://docs.oracle.com/javase/tutorial/essential/concurrency/immutable.html But I'm sure others have already pointed this out. I'll get my coat :-) lipska -- Lipska the Kat©: Troll hunter, sandbox destroyer and farscape dreamer of Aeryn Sun
