SynchronizationException object and interrupt the waiting thread. This exception should be a derived class of RuntimeException, so that it does not have to be specially processed.The main problem with recommended methods for changing synchronized syntax is that they need to be modified at the binary code level. Currently, these codes use the enter-monitor and exit-monitor commands to implement synchronized
is a method in the object class. When a thread executes the wait () method, it enters a waiting pool related to the object and loses (releases) the machine lock of the object (the machine lock is temporarily lost, and the object lock needs to be returned after the wait (long timeout) Timeout time is reached); other threads can access it;Wait () uses Y, yyalll, or the specified sleep time to wake up threads in the current waiting pool.Wiat () must be
of the call stack needs to process the interrupt after the non-canceled task ends. Listing 6 shows a method that waits for a blocking queue until an available item appears in the queue, regardless of whether it is interrupted. To make it easier for others, it resumes the interrupt state in a finally block after the end, so as not to deprive the caller of the interrupt
with, is not return, B thread may be able to wait, want to interrupt themselves, no longer wait for this lock, to deal with other things. This time Reentrantlock provides 2 mechanisms, first, the B thread interrupts itself (or another thread interrupts it), but Reentrantlock does not respond, continue to let the B

pool is concerned, the term "thread pool" is somewhat misleading because the thread pool "obvious" implementations do not necessarily produce the results we want in most cases. The term "thread pool" appears before the Java platform, so it may be the product of less object-oriented methods. However, the term continues
