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.
