I need to uniquely identify messages in my app. Thus each message should contain its id. I have a couple of questions though..

  1. Should message generate its id privately and only provide getter for id?
  2. What is the best way to create ids? Any alternatives to UUID class in java?

Thanks.

    1. Obviously, the ID should not have a public setter. An alternative to having the message generate the ID itself is to pass it in the constructor.
    2. If your app is distributed, there is no real alternative to a UUID. If it’s not distributed, AtomicInteger or AtomicLong are good alternatives that can be used concurrectly without locking.
