抽象类

0）可能定义你的类必须实现的属性和方法如果它不是你的类不是抽象的。

1）可以有属性，方法和构造函数的实现

解决方案

C'mon use google, it's full of all such examples and discussions:

Abstract Class versus Interface[^]

An interface defines properties and methods that your class must implement.

An abstract class
0) may define properties and methods that your class must implement if it's not your class is not abstract.
1) can have implementations of properties, methods and constructors

Any class can only inherit from one other class (abstract or not), but can implement multiple interfaces.
