kotlin fun main { val items = listOf("apple", "banana", "cherry") for ((index, item) in items.withIndex()) { println("Index: $index, Item: $item") } } 在这个例子中,withIndex() 函数被用来给 items 列表的每个元素添加索引。然后,在 for 循环中,我们使用解构声明 (index, item) 来...
Ruby Kotlin Python Java It's possible to iterate through an array with an index. For example, funmain(args:Array<String>){varlanguage = arrayOf("Ruby","Kotlin","Python","Java")for(iteminlanguage.indices) {// printing array elements having even index onlyif(item%2==0) println(language...

println("[$index] - $element") } } Output [0] - apple [1] - banana [2] - cherry Conclusion In thisKotlin Tutorial, we learned how to iterate over elements of an Array using For Loop, in Kotlin programming language with examples....
在Kotlin中编写复杂的for循环可以通过多种方式实现,包括使用范围、步长、条件判断以及嵌套循环等。以下是一些常见的复杂for循环的示例及其解释: 1. 基本for循环 基本的for循环用于遍历一个范围内的数字或者集合中的元素。 代码语言:txt 复制 for (i in 1..10) { println(i) } 2. 使用步长 如果你需要以特定的...

list长度为5，index打印从0到4，不包括list.size这个。list长度为5，index打印从0到5，包括list.size这个。方式1常用在遍历集合，不过Kotlin另外提供了很好遍历集合的方式，例如 以上分析有不对的地方，请指出，互相学习，谢谢哦！
