How do you want to compare? Thread-Safe is a feature but, Synchronization is a method/procedure to do it.

Thread safe definition here http://en.wikipedia.org/wiki/Thread_Safe.

Synchronisation is a language feature you might use to achieve thread safety (if you use it right ;-) )

Another way of providing thread safety instead of synchronization can be accomplished by using classes from the java.util.concurrent.locks package.
It is similar to synchronization (lock on an Objects monitor) but using locks the locks can be released in a different order then obtaining them.
