Let's create a million coroutines again, keeping their Deferred objects. Now there's no need in the atomic counter, as we can just return the numbers to be added from our coroutines: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 val deferred = (1..1_000_000).map { n -> async...
1.使用arrayOf创建数组,必须指定数组的元素,可以是任意类型 //1.使用arrayOf创建数组,必须指定数组的元素,可以是任意类型 val arrayNumber= arrayOf(1,2,3,4) //集合中的元素可以是任意类型 //kotlin中的Any等价于Java中的Object 对象的意思 val arrayObjects:Array<Any> = arrayOf(1,true,"2") 1. 2. ...
4、可变长参数函数可以使用"vararg"关键字标识类似Java中的public void setData(Object... objects)。 fun vars(vararg args: Int) { for (arg in args) { print(arg) } } 5、lambda(匿名函数) val sumLambda: (Int, Int, Int) -> Int = { a, b, c -> a + b + c } 测试 println("sum ...

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 ...
