collection sublist

hi,

I was running following example

import java.util.*;

public class d {
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));
}
}

from link
http://www.tutorialspoint.com/javaexamples/collection_sublist.htm
Iam getting output as

List :[one-Two, three, Four, five, six, one, three, Four]
SubList :[three, Four]
indexOfSubList: 1
lastIndexOfSubList: 6

I have not understood meaning of sublist its index concept

>> List sublist = Arrays.asList("three Four".split(" "));

what above line do .

Why

indexOfSubList: 1
lastIndexOfSubList: 6

is getting printed.

Any ideas, suggestions, sample code, links, source code highly appreciated. Thanks in advance

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: "
