If we will use synchronization over a method in that case whole code will get synchronize but if we use synchronize block in that case only that part of the code will get synchronize which is accessing the object. So synchronize block provide you better performance that synchronize method

You'd use a synchronized block if you only needed part of a method's code to be locked for multi-threaded access.

A synchronized method locks all of the method's code, so that only one thread can enter it at a time.
