Java 实例 - List 截取
以下实例演示了如何使用 Collections 类的 indexOfSubList() 和 lastIndexOfSubList() 方法来查看子列表是否在列表中，并查看子列表在列表中所在的位置：

import java.util.*;
public class Main {
public static void main(String[] args) {
List list = Arrays.asList("one Two three Four five six one three Four".split(" "));
System.out.println("List :"+list);
List sublist = Arrays.asList("three Four".split(" "));
System.out.println("子列表 :"+sublist);
System.out.println("indexOfSubList: "
+ Collections.indexOfSubList(list, sublist));
System.out.println("lastIndexOfSubList: "
+ Collections.lastIndexOfSubList(list, sublist));
}
}
以上代码运行输出结果为：
List :[one, Two, three, Four, five, six, one, three, Four]
子列表 :[three, Four]
indexOfSubList: 2
lastIndexOfSubList: 7
