dealing with multiple tasks at the same time. Many programming problems require that the program be able to stop the work being done, turn to some other problem, and then return to the main process.We can improve the responsiveness of the program by splitting the task into several separate parts. These concepts are called "concurrency" in the program, which are called threads by the parts that run independently of each other.But there is one hidden d

methods. ② down transformation and runtime type recognitionAs the upward transformation loses the specific type information, we think that by going down the transformation should be able to get type information, in the Java language, all transformations will be checked. If the type does not match, a classcastexceptionis returned. This behavior of checking the type during run is called Runtime type recognition (RTTI).5. Summary Polymorphism means "di
