推荐答案
Animal 是泛化，Dog 是特化.您的超类是一个通用类，但您的子类将是您的超类的专门继承者.随着您在继承层次结构中向下移动，它会变得更加专业化和普遍化.
Animal is a generalization , Dog is specialization. Your superclass is a generalized class , but your subclass will be a specialized inheritor of your superclass. It becomes more specialized and less generalized as you move down the inheritance hierarchy .
泛化是从两个或多个类中提取共享特征，并将它们组合成一个泛化超类的过程.共享特征可以是属性、关联或方法.
Generalization is the process of extracting shared characteristics from two or more classes, and combining them into a generalized superclass. Shared characteristics can be attributes, associations, or methods.
如果从现有的超类创建一些新的子类来完成超类的特定工作，则称为特化.
If some new subclasses are created from an existing superclass to do specific job of the superclass, then it is known as specialization.
