Java Object Level Synchronization

Object Level Synchronization comes into the picture when two or more using the same Object Or shared a resource across the multiple threads. Without synchronization there is a heavy chances of the data might go into inconsistent state.

Synchronization is the only way to avoid the data inconsistency of a Shared resource or an object, synchronization is a concept which prevents accessing the shared resource or an object by multiple threads at a time.

Synchronization allows only one thread can access the resource at a time. In Java synchronization can be achieved by using the keyword synchronized.

Every object in a Java possesses a lock, synchronized block or method allows to acquire a lock of an object by only one thread at a time. Once the thread is completed the execution of that synchronized block or method then the lock of that object will be released for other threads.
