以下實例示範如何使用Collections 類別的indexOfSubList() 和lastIndexOfSubList() 方法來查看子列表是否在列表中,並查看子列表在列表中所在的位置:
/* author by w3cschool.cc 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)); } }
List :[one, Two, three, Four, five, six, one, three, Four] 子列表 :[three, Four] indexOfSubList: 2 lastIndexOfSubList: 7
