一个抽象类可以扩展另一个抽象类并增加功能吗
我有一个抽象类.我想通过另一个抽象类扩展抽象类，然后实现扩展的抽象类.是否可能.如果是，从 OOPS 的角度来看，这是否是一种好方法?
I have an abstract class. I want to extend the abstract class by another abstract class and then implement the extended abstract class. Is it possible .If yes, whether it's a good approach in point of view regarding OOPS?
我不太清楚 Java，但它应该是有效的.
I'm not sure about Java in particular, but it should be valid.
就OOP而言，如果它有意义，那么就运行它.要使用一些旧示例，您可能有一个 Vehicle 抽象类，然后是 LandVehicle 和 FlyingVehicle 抽象类.只要您的示例作为抽象类有意义，那么您应该没问题.
In terms of OOP, if it makes sense, then run with it. To use some old examples, you might have a Vehicle abstract class and then LandVehicle and FlyingVehicle abstract classes. As long as your example makes sense as an abstract class, then you should be fine.
