Java 实例 – List 循环移动元素
Java 实例
以下实例演示了如何使用 Collections 类的 rotate() 来循环移动元素,方法第二个参数指定了移动的起始位置:
/* author by w3cschool.cc Main.java */ import java.util.*; public class Main { public static void main(String[] args) { List list = Arrays.asList("one Two three Four five six".split(" ")); System.out.println("List :"+list); Collections.rotate(list, 3); System.out.println("rotate: " + list); } }
以上代码运行输出结果为:
List :[one, Two, three, Four, five, six] rotate: [Four, five, six, one, Two, three]
