数据类是 Kotlin 在实现 Value Objects 时使用的方法,以减少 Java 中不可避免的样板问题。 例如,在 Kotlin 中,你只写一个 Value Object : data class User(val name: String, val age: Int) Kotlin 对 equals()、hashCode()、toString() 以及 copy() 有很好的实现。在实现简单的DTO 时它非常有用。但请...
数组类型 定义如:valx:IntArray=intArrayOf(1,2,3) 2.6 Strings 字符串类型 定义如:vals="Hello, world" 3.基本语法 3.1 if语句 3.2 when语句(替代了java里的switch) 3.3 for循环语句 循环遍历集合collection里面的数据 并输出 3.4 while 和 do...while语句和java类似 ...
Text rendering:Render objects to strings using text renderers. Text renderers are controlled via theTextRenderersProcessormethod, and you can access the method with thenotebook API entry point. A library can define one or more renderers. The Kotlin Kernel iterates until at least one renderer ...
