synchronization (thread-safe) when two or more processes concurrently manipulate the same resource, only one thread is allowed to access at the same time, and other threads wait.14, the keyword synchronized synchronization, can be used as a modifier of the method, indicating that when a thread is accessing the resource, other processes can only wait. When the thread ends access to the resource, other threads are allowed access.15, the result of synchronization: Data security, low efficiency.16,
