问题描述
我有一个类（我们称之为 A ），它由几个子类扩展（ B ， C ， D 等）。
I have a class (let's call it A) that is extended by several children class (B, C, D, etc.).
在每个子类中，我都希望从父类的实例化中访问特定的方法 A 。
In each child class, there are specific methods that I'd like to be accessible from an instantiation of the parent class A.
我试图将 A 声明为抽象类，并将每个子类方法声明为抽象。然后我在他们自己的类中实现了这些方法，但似乎每个子类必须实现父类的每个方法。但是，我不能这样做。
I tried to declare A as an abstract class, and to declare each child class methods inside as abstract. Then I implemented these methods in their own class but it seems that each child class must implement every method of the parent class. However, I can't do this.
您对此问题有所了解吗？
Would you have an idea for this issue?
推荐答案
在每个子类中，有一些特定的方法，我希望可以从父类A的实例化。
这不是继承点。即使你能做到这一点，也表明你的设计已被打破。
That's not the point of inheritance. Even if you could do this, it shows that your design is broken.
