In middle November, I felt that I could not drag it down, so I started the course of research again. First of all, I spent about two weeks giving K a book and a question.

the same type call the same method and present different behavior characteristics. This is polymorphism. It should be noted that the referenced variable can only call the method of its type during compilation, while the method of its runtime type is executed during execution. In the code above, if the car variable executes the run () method, it cannot be compiled because the car type does not have the run () method during compilation. Although the car variable points to an object, it does have

Otherwise, a classcastexception exception is reported during the execution even though it can be passed during compilation. 4.

When an object is born at a level of the pyramid, it can only survive at this level or lower level of birth. Even if it changes to a disguise, although it can be used for a while, it will inevitably show up because of insufficient skills when it is really working. However, there are also some real super objects, although they are natural
