Collections Class lastIndexOfSubList() method

  • lastIndexOfSubList() method is available in java.util package.
  • lastIndexOfSubList() method is used to return the starting index of the last occurrence of the given (dest) list within the given source list (src).
  • lastIndexOfSubList() method is a static method, so it is accessible with the class name and if we try to access the method with the class object then we will not get an error.
  • lastIndexOfSubList() method does not throw an exception at the time of returning the index of the last occurrence of the given List (dest).


    public static int lastIndexOfSubList(List src, List dest);


  • List src – represents the source list in which to filter the last occurrence of the given list(dest).
  • List dest – represents the targeted list(dest) to filter sublist of the given source list(src).

Return value:

The return type of this method is int, it returns starting index of the last occurrence of the given sublist (dest) within the given source list(src) otherwise it returns -1 when no search found or list empty.


// Java program is to demonstrate the example
// of int lastIndexOfSubList() of Collections

import java.util.*;

public class LastIndexOfSubList {
    public static void main(String args[]) {
        // Instantiate a LinkedList   
        List src_l = new LinkedList();
        List dest_l = new LinkedList();

        // By using add() method is to
        // add elements in linked list src_l

        // By using add() method is to
        // add elements in linked list dest_l

        // Display LinkedList
        System.out.println("link_l: " + src_l);
        System.out.println("dest_l: " + dest_l);


        // By using lastIndexOfSubList() method is to
        // return the starting index of last occurrence
        // of dest_l in src_l
        int index = Collections.lastIndexOfSubList(src_l, dest_l);

        //Display index
        System.out.println("Collections.lastIndexOfSubList(src_l,dest_l): " + index);


link_l: [10, 20, 30, 40, 50]
dest_l: [40, 50]

Collections.lastIndexOfSubList(src_l,dest_l): 3
