在Kotlin同时扩展和实施 [英] Extend and implement at the same time in Kotlin

问题描述

在Java中，你可以这样做：

In Java, you can do such thing as:

class MyClass extends SuperClass implements MyInterface, ...

是否有可能在Kotlin做同样的事情？假设 SuperClass 是抽象的并且没有实现 MyInterface

Is it possible to do the same thing in Kotlin? Assuming SuperClass is abstract and does not implement MyInterface

推荐答案

界面实施和<之间没有语法差异a href =https://kotlinlang.org/docs/reference/classes.html#inheritance =noreferrer>类继承。只需列出以冒号：后逗号分隔的所有类型，如下所示：

There's no syntactic difference between interface implementation and class inheritance. Simply list all types comma-separated after a colon : as shown here:

abstract class SuperClass
interface MyInterface

class MyClass : SuperClass(), MyInterface, Serializable

禁止多类继承，而单个类可以实现多个接口。

Multiple class inheritance is prohibited while multiple interfaces may be implemented by a single class.
