Fix this java code

I have the following assignment that I have worked on but I need fixed. Please only bid if you can complete this in about 1 hour from the time I award the project. Part I: Write a DoublyLinkedList Your list should contain inner classes private class Node and public class Iterator Your list should include the following routines: public void insert( AnyType data ) public void remove( AnyType data) public int size() public Iterator first() public Iterator last() public Iterator find(AnyType data) Your Iterator should include the following routines: public bool valid() public void next() public void prev() public AnyType getData() public void remove() // removes "current" from the list public void insert(AnyType data) // inserts after "current" My code is package linked_list; /** * @author adamb */ public class LinkedList<AnyType>{ public class ListNode { AnyType data; ListNode next; ListNode previous;//Make a previous to access the previous node. public ListNode(AnyType data, ListNode next, ListNode previous) {//Make three parameter method to access both the previous and the next node.(Doubly linked list) [login to view URL] = data; [login to view URL] = next; this.previous=previous;}}//Set the previous node as the object's previous node. ListNode header; ListNode footer;//Make footer to easily access to the last node. public LinkedList() { header = new ListNode(null, null, null); footer=new ListNode(null,null,null); } public void add(AnyType data) { [login to view URL] = new ListNode(data, [login to view URL], [login to view URL]);}////////////3 parameter method. public boolean remove(AnyType data) { ListNode current = [login to view URL]; current=[login to view URL];//////////////////// while (current != null && [login to view URL] != null && ) current = [login to view URL]; if (current != null && [login to view URL] != null&&[login to view URL]!=null&&[login to view URL]!=null) { current.previous.next=[login to view URL]; current.next.previous=[login to view URL]; return true; } return false; } public ListIterator<AnyType> first() { return new ListIterator<AnyType>([login to view URL]);}//It is recursion method to iterate the process. public int size() { ListNode current = [login to view URL]; int s = 0; while (current != null) { s++; current = [login to view URL];} return s;} boolean contains(AnyType data) { ListIterator<AnyType> i = first(); while ([login to view URL]()) { if ([login to view URL]().equals(data)) return true; [login to view URL]();} return false;} public void replace (AnyType data1, AnyType data2) { ListNode current = [login to view URL]; while (current != null && ) current = [login to view URL]; if (current != null) [login to view URL] = data2;} public static class ListIterator<AnyType>{//Can access from main(), it must declared 'static'. It is because 'static' can access to 'static'. LinkedList<AnyType>.ListNode current; ListIterator(LinkedList<AnyType>.ListNode n) { [login to view URL] = n;} public boolean valid() { return current != null;} public AnyType Data() { if (current != null) return [login to view URL]; else return null;} public void next() { if (current != null) current = [login to view URL];}} public static void main(String args[]) { LinkedList<Integer> l = new LinkedList<Integer>();//Make an object. [login to view URL](new Integer(5)); [login to view URL](new Integer(55)); [login to view URL](new Integer(555)); [login to view URL](new Integer(55)); if ([login to view URL](new Integer(555))) [login to view URL]("yes"); else [login to view URL]("no"); [login to view URL](new Integer(5), new Integer(45)); ListIterator<Integer> iter = [login to view URL](); while ([login to view URL]()) { [login to view URL]([login to view URL]()); [login to view URL]();}}} And the result is yes 555 55 45 I can't remove the node.. I don't know what's wrong though.
