如何找到列表的一個子列表？

解決方法

下麵的示例使用indexOfSubList()＆lastIndexOfSubList()來檢查子列表是否有在清單或不，找到子列表在列表的最後。

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("SubList :"+sublist);
      System.out.println("indexOfSubList: "
      + Collections.indexOfSubList(list, sublist));
      System.out.println("lastIndexOfSubList: "
      + Collections.lastIndexOfSubList(list, sublist));
   }
}

結果

上麵的代碼示例將產生以下結果。

List :[one, Two, three, Four, five, six, one, three, Four]
SubList :[three, Four]
indexOfSubList: 2
lastIndexOfSubList: 7
