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 shouce.ren
- 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]
