步骤2:在 Kotlin 类中使用in和!in代替 Java 中的contain语法 在Kotlin 中,我们可以使用in来代替 Java 中的contain语法。下面是一个示例代码: vallist=listOf(1,2,3,4,5)if(3inlist){// 使用 in 来判断元素是否在列表中println("3 is in the list")}if(6!inlist){// 使用 !in 来判断元素是否不...
LinkedList:基于双向链表实现,支持快速的插入和删除操作,但随机访问速度较慢。 List<Integer>arrayList=newArrayList<>();List<Integer>linkedList=newLinkedList<>();// 添加元素arrayList.add(1);linkedList.add(1);// 随机访问System.out.println(arrayList.get(0));// 快速System.out.println(linkedList.get(0)...

用contain 函数的编程语言有很多,比如 C++、Java、Python 等, 但是它们实现的方式有所不同。比如,在 C++中,contain 函数可以 用“string.find()”取代,以便快速查找一个字符串中是否包含另一 个字符串。在 Java 中,可以使用“string.contains ()”,而在 Python 中,可以使用“in”运算符。 使用contain 函数可以...
