kotlin的loop和Range、list和map 继续学习Kolin的基础语法,比较简单,直接练习代码。 loop和range: 这里用一个场景来说明:计算从1到100之间数的总和,那在kotlin中是如何搞的呢? 上面这么简单的一句代码确实是能表达么?下面输出看一下就知道了,这里就涉及到怎么循环了,其实跟java差不多,如下: 编译运行: 确实是能表...

The destructuring declaration gives us access to the key and value of each entry as we iterate over the map. 3.5. Functional Style Iteration Using forEach So far, we looked at the traditional style of iterating over arrays, collections, and ranges using the for loop. To code in a function...
Map<String, Int>的泛型类型是从传递给Pair构造函数的参数的类型推断出来的。我们可能会想知道,如果用于创建map的推断类型的对不同会发生什么?第一对是Pair<String, Int>,第二对是Pair<String, String>: var map = mapOf("Mount Everest" to 8848, "K2" to "4017") ...

With theforEachIndexedmethod, we loop over the list having index and value available in each iteration. val it: ListIterator<String> = words.listIterator() while (it.hasNext()) { val e = it.next() print("$e ") } The final way is using aListIteratorand awhileloop. ...
