Threads - Why a Lock has to be followed by try and finally

Question

A Lock is always followed by a try/finally block, why?

ReentrantReadWriteLock readWriteLockBitmap = new ReentrantReadWriteLock();
Lock read = readWriteLockBi         


        

Answer 1

To make sure that whatever happens, even if an exception is thrown, you will still unlock the locked stream before leaving the method.
