为什么我们需要界面？ [英] why we need interface?

问题描述

我们可以使用抽象类而不是接口。抽象类有抽象和非抽象方法可用。为什么我们需要接口。你可以说在单个类中实现多个接口。我们可以有单个抽象类并继承到另一个类。

请用例子清楚地解释我。

Hi,

we can use abstract class instead of interface. abstract class have abstract and non abstract methods are available. why we need interface. You can say like implement multiple interface in single class. we can have single abstract class and inherit to another class.
please explain me clearly with example.
