Java – Spring RabbitMQ get all declared queues

Yes, finally will be called after the execution of the try or catch code blocks.

The only times finally won't be called are:

1. If you invoke System.exit()
2. If you invoke Runtime.getRuntime().halt(exitStatus)
3. If the JVM crashes first
4. If the JVM reaches an infinite loop (or some other non-interruptable, non-terminating statement) in the try or catch block
5. If the OS forcibly terminates the JVM process; e.g., kill -9 <pid> on UNIX
6. If the host system dies; e.g., power failure, hardware error, OS panic, et cetera
7. If the finally block is going to be executed by a daemon thread and all other non-daemon threads exit before finally is called

Yes, Blah.valueOf("A") will give you Blah.A.

Note that the name must be an exact match, including case: Blah.valueOf("a") and Blah.valueOf("A ") both throw an IllegalArgumentException.

The static methods valueOf() and values() are created at compile time and do not appear in source code. They do appear in Javadoc, though; for example, Dialog.ModalityType shows both methods.
