Java 實例 - List 截取

Java 實例 Java 實例

以下實例演示了如何使用 Collections 類的 indexOfSubList() 和 lastIndexOfSubList() 方法來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:

/*

 Main.java
 */

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));
   }
}

以上代碼運行輸出結(jié)果為:

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