JAVA-Multithreading synchronization

Multi-threaded synchronization

1. Lock object.

Scenario: When a data may be modified by another thread, lock the method that involves the data, and ensure that only the thread that owns the lock can access the data at the same time, and that the other thread that calls the method is blocked. Note: The same object must be accessed by different threads, with the same lock object.

Application Method:

　　

 Public class bank{    privatenew  reentrantlock ();      Public void Transfer ()    {        banklock.lock ();                 Try         {             ....             }         finally         {            banklock.unlock ();}}    }
