See what's being passed here into the synchronized block. It is the monitor object. In this example, the monitor object is the this or current object. In other words, it says, use the current object's monitor as the monitor object for synchronizing the block of code. It doesn't always have to be this. It can be any object's monitor on which you want to synchronize the code. On the other hand, if it was a synchronized method, like in line 24, the monitor object is implicitly the monitor of the current object to which the method belongs as it is an instance method. In either case, we are talking about an instance or object level lock. That is, the critical code is protected by the monitor of a given object. This means that other objects can still access the synchronized code. If class-level synchronization is needed, the synchronized…
