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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
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:
1 2 3 4 | List :[one, Two, three, Four, five, six, one, three, Four]
子列表 :[three, Four]
indexOfSubList: 2
lastIndexOfSubList: 7
