在Android Kotlin中,使用for-loop创建多个对象是一种常见的操作,尤其在需要初始化一组相似对象时。以下是如何实现这一操作的步骤和示例代码。 基础概念 循环:在编程中,循环是一种控制结构,它允许代码块重复执行多次。 对象创建:在面向对象编程中,对象是通过类实例化得到的。 优势 代码简洁:使用循环可以减少重...
Unlike Java and other programming languages, there is no traditional for loop in Kotlin.In Kotlin, the for loop is used to loop through arrays, ranges, and other things that contains a countable number of values.You will learn more about ranges in the next chapter - which will create a ...
for在Kotlin—中循环的语法是: for (item in collection) { // body of loop } 身体 for (item: Int in ints) { // body of loop } 示例代码 for (i in 0..5) { println(i) // 0,1,2,3,4,5 --> upto 5 } 要么 for (i in 0 until 5) { println(i) // 0,1,2,3,4 --> ...
The for loop in Kotlin is used to iterate or cycle though the elements ofarray,ranges, collections etc. In this guide, we will learn how to use for loop in Kotlin with the help of various examples. A simple example of for loop in Kotlin In the following example we are iterating though...
In this tutorial, you shall learn how to iterate over the elements of a given array using For loop in Kotlin, with examples. Kotlin Array – For Loop To iterate over elements of an Array in Kotlin, we can use For Loop. Inside the For Loop body, we can access respective element of th...
在Kotlin中,for循环用于遍历范围,数组,映射等(提供迭代器的任何对象)。 Kotlin 中for循环的语法是: for (item in collection) { //循环体 } 示例:遍历范围 示例 fun main(args: Array<String>) { for (i in 1..5) { println(i) } } 在这里,循环遍历范围并打印单个项目。
在Kotlin中,如下所示,我找到了一个解决方案,其中强制索引i在循环块之外具有作用域。此外,i++行在某种程度上被掩埋,并与循环结构分离。在这种情况下,我缺少优雅的Kotlin语法,比如'builders',没有分号等。我谦虚地认为,这是因为for-loop流程控制结构在Kotlin中的表达能力较差。诚然,这并不关键,但更多的是令人失望。
Kotlin中有两个索引的for循环 kotlin for-loop nested-for-loop 可以在Java、e.g中使用具有双索引的for循环: for (int j = 0, k = myArray.length - 1; j < myArray.length; j++, k--) 使用j从第一个元素迭代myArray元素,同时使用k从最后一个元素迭代,而不使用内部循环。我们如何在Kotlin中实现...
[Kotlin] for loop fun main() { val list= listOf("Java", "Kotlin", "Python")for(element in list) { println(element) }for((index, value) in list.withIndex()) { println("Elmenet at $index is $value") }/** Elmenet at 0 is Java Elmenet at 1 is Kotlin Elmenet at 2 is ...
I want to start a For loop from a given index in Java you can easily write for (int i = startingIndex; i < items.size(); i++) how to to do that in Kotlin? I know how to write a for loop in Kotlin my example I want to iterate over an array of strings but the start...
