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：

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]
