Answer 1

1. Wikipedia is a great resource for any Computer Science student. Here is an article on Non-blocking synchronization - http://en.wikipedia.org/wiki/Non-blocking_synchronization

2. Non-blocking synchronization is available in any language, it is how the programmer defines their multi-threaded application.

3. You should only use locking (i.e. synchronized (list) ) when necessary due to the time it takes to acquire the lock. In Java, the Vector is a thread safe data structure that is very similar to Java's ArrayList.
