Editor to share with you what is the difference between syncronized and Lock, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Lock is an interface; synchronized is a keyword in Java, with built-in language implementation

When an exception occurs in synchronized, the lock held by the thread will be automatically released, so the abnormal deadlock will not occur; when an exception occurs in lock, if the lock is not released actively through the unlock () method, the lock will always be occupied and deadlock will occur, so the lock needs to be released in the finally block.

Lock can make the thread waiting for the lock respond to the interrupt; not synchronized, the waiting thread will wait forever.

You can know whether the lock has been acquired successfully through lock; synchronized is not allowed

Lock can improve the efficiency of multiple threads for reading operations.

Add:

In terms of performance, if the competition for resources is not fierce, the performance of the two is similar, but when the competition is very fierce, the performance of lock is much higher than that of synchronized.
