Principles and skills of concurrent programming

1. The principle of single responsibility. Separate concurrent related code from other code.

2. Limit the scope of data. Two threads may interfere with each other when they modify the same field of a shared object, resulting in unexpected behavior. One solution is to construct critical sections, but the number of critical sections must be limited.

3. Use data copies. Data replicas are a good way to avoid sharing data, and replicated objects are only treated as read-only.

4. Threads should be as independent as possible. Let threads exist in their own world and do not share data with other threads.
