java - Extend and implement at the same time in Kotlin

Question

In Java, you can do such thing as:

class MyClass extends SuperClass implements MyInterface, ...

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

Answer 1

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

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