It is common in object-oriented development to abstract out a common interface that may have multiple implementations and write code that works with the interface, making it more reusable.
在面向对象的开发中，有一种实践很常见：抽象出一个可能拥有多个实现的接口并编写代码以使用该接口，从而使其可以重复利用。
Extensible framework - Common functions and features are abstracted as loosely coupled abstract classes and interfaces, which can be extended to provide application-specific implementations.
