Java 实例 - List 循环移动元素
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:
Main.java 文件
importjava.util.*;
publicclassMain{publicstaticvoidmain(String[]args){Listlist = 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]
