The synchronized keyword is a modifier that locks a method so that only one thread can use it at a time. This prevents problems that arise from race conditions between threads.

Synchronization is a process of controlling mutual exclusive problem in multithreading environment. Only one thread can access a resource at a particular instance of time. When a thread accesses a synchronized block or method, it acquires a lock on it and release the lock either after completion of method/block or any exception occur. Note ...
