    Post Lisp Lists in java

    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.
