Lisp Lists in java

[ir9]

Hello, I have made an attempt at writing this code but it doesn't seem to do much, am kind of new to the concept of lisp lists therefore i believe i don't quiet understand what i should be doing, anyways here is what i have tried:

import java.util.*;
public class removNum{
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        LispList<Integer> list;
        System.out.println("Enter a list (of integers): ");
        String str = in.nextLine();
        list = removePos(list);
        System.out.println(list); 
    }
    public static LispList removePos(LispList list, int n){
        if(0==n){
            return list.getTail();
        }
        else{
            return new LispList(list.getHead(),removePos(list.getTail(),n-1));
        }
    }
}

Well basically what i'm trying to do is to write a recursive method which takes a list and an integer x, and deletes the integer at position x in the list, e.g. if the list is [2,5,6,40,8,9,45] and the integer is 40, the method should return [2,5,6,40], so nothing after the integer should be printed.
I don't expect anyone to write up the solution for me but a nudge in the right direction would be greatly appreciated.

i am not sure but trying to give replay...
LispList is not available in any package....

Look at this link for lisp list details
DCS128: Lisp Lists notes
Looking through this, i'm trying to do something along those lines

i think jvm is not able to undestand the lisplist why because no jvm vendor provided...
