java - 如何在一行中打印 Kotlin 中字符串数组的所有元素？

Question

这是我的代码

    fun main(args : Array<String>){
     var someList : Array<String> = arrayOf("United","Chelsea","Liverpool")

      //How do i print the elements using the print method in a single line?
    }

在java中我会做这样的事情
someList.forEach(java.lang.System.out::print);

Answer 1

Array 有一个 forEach 也可以采用 lambda 的方法:

var someList : Array<String> = arrayOf("United","Chelsea","Liverpool")
someList.forEach { System.out.print(it) }

或方法引用:

var someList : Array<String> = arrayOf("United","Chelsea","Liverpool")
someList.forEach(System.out::print)
