The theoretical knowledge is boring, but these are basic skills and may be forgotten after learning. However, when used, we will find that the previous learning is very meaningful, and the learning thread is like this. 1. how to Create a lock? Lock lock = new ReentrantLock (); 2. How to Use the Lock? See the Lock document. The format is as follows: class X {private final ReentrantLock lock = new ReentrantLock ();//... public void m () {lock. lock ();
