Threadsafe vs Synchronized

Question

I\'m new to java. I\'m little bit confused between Threadsafe and synchronized. Thread safe means that a method or class instance can be used by multiple threads at the same tim

Answer 1

Nayak, when we declare a method as synchronized, all other calls to it from other threads are locked and can wait indefinitely. Java also provides other means of locking with Lock objects now.

You can also declare an object to be final or volatile to guarantee its availability to other concurrent threads.
