When an object becomes unreachable, it is flagged as collected by
the garbage collector. If it has a finalize() method, it is marked
for finalization and put in a finalization queue. After
finalization, it becomes finalized. If it does not have a finalize() method,
it is directly marked as finalized without being inserted in
the finalization queue.

A high-level programming language developed by Sun Microsystems. Java was originally called OAK, and was designed for handheld devices and set-top boxes. Oak was unsuccessful so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web.
Java is an object-oriented language similar to C++, but simplified to eliminate language features that cause common programming errors.
