interface MyInterface { val property: String // 抽象属性 val anotherProperty: String get() = "Default implementation" // 具有默认 getter 的属性 } 1. 2. 3. 4. 5. 在这个例子中,property是一个抽象属性,必须在实现接口的类中被实现。anotherProperty则有一个默认的getter实现,可以在子类中选择性地...
DefaultImpls.speak(this); } }The Kotlin compiler generates the DefaultImpls class with the speak method. This method contains the default implementation. It takes an instance of an interface as a parameter and interprets it as this (in case you call other members of this interface inside)....

interface study2{ fun readBooks() fun doHomework() { println("do homework default implementation.") } } 可以看到给doHomework加上了函数体, 如果一个接口中函数有了函数体,这个函数体中的内容就是它的默认实现,现在当一个类去实现study接口时, 只会强制要求实现readBooks函数, 对doHomework没有强制要求....
Keyword interface is used to define interfaces in Kotlin. For example, interface MyInterface { var test: String // abstract property fun foo() // abstract method fun hello() = "Hello there" // method with default implementation } Here, an interface MyInterface is created. the interface has...
