The degree between these choices is related to the basic expectation of investment, the choice of risks and profits, opportunity cost, etc.The third adapter mode is the adapter mode of the interface, The adapter for the interface is as follows: Sometimes we write an interface with multiple abstract methods, When we write the implementation class for the interface, All methods of the interface must be implemented, This is obviously wasteful at times, Because not all methods are what we need, Sometimes only a few are needed, In order to solve this problem here, we have introduced the adapter mode of the interface. With the help of an abstract class, the abstract class implements the interface and all methods. However, we do not deal with the original interface, but only get in touch with the abstract class, so we write a class, inherit the abstract class and rewrite the methods we need.
