call the garbage collector. Besides, the logic of the garbage collector cannot ensure that all expired data is deleted from the heap during a garbage collection process, it is powerless for unmanaged objects (such as file handles, network connections, and database connections) that are not managed by the garbage collector. What should we do?In this case, you need to develop special rules to ensure that unh
