在构造对象过程中,有三个地方可以对成员进行初始化:1)是在首构造方法( Primary constructor);2)是在声明成员的同时进行初始化,或者是在初始化代码块(init {...})中;3)是在次要构造方法(Secondary constructor)中。 要注意它们之间的区别和执行顺序,首构造方法是最先执行的,但它不能运行代码,只能进行赋值;成员...

扩展阅读Properties。 函数式接口 接口(interfaces)是更高级别的抽象,专注于行为的抽象,用以实现对象间契约式行为交互。这一部分不打算详细讲解interface的使用,而是重点关注函数式接口(function interface)。Kotlin中的接口与Java 8中的接口是一样的,不再全是抽象方法了,可以有默认方法,也就是对接口的方法添加默认的实...

For a more in-depth comparison between Scala and Kotlin you can see our article:Kotlin vs Scala: Which Problems Do They Solve? Why not keeping usingJava? Java is a good language but has a series of issues because of its age and success: it needs to maintain backward compatibility with a...
No binary compatibilityCopy heading link A major change with the new IR compiler backend is the absence of binary compatibility with the default backend. A lack of such compatibility between the two backends for Kotlin/JS means that a library created with the new IR compiler backend can’t be...
