The constructor is called automatically when the object is generated. Whenever a definition object is found, the timing of the constructor call is found. objects of different scopes have different life cycles, such as local objects, global objects,

One, the reason for using threads1. You can use threads to isolate code from other code to improve application reliability.2. You can use threads to simplify coding.3. Threads can be used to implement concurrent execution.II. Basic Knowledge1,
