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

问题描述

在 Java 中，您可以执行以下操作:

In Java, you can do such thing as:

class MyClass extends SuperClass implements MyInterface, ...

是否可以在 Kotlin 中做同样的事情?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

interface 之间没有语法差异实现和类继承.只需在冒号后以逗号分隔列出所有类型 : 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 MySuperClass
interface MyInterface

class MyClass : MySuperClass(), MyInterface, Serializable

禁止多类继承，一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.
