stucking in dealing the cards of my CardDeck Class which takes Object as a parameter

I tryign to continue in coding my game but have problems with my CardDeck class.
when I tried to code the Deal method in my CardDeck class, I couldn't use add and remove method from my LinkedList class to add a card to my new hand and then remove it from the deck( my add & remove methods are taking objects).

below is my program code with all classes.


****** Card Clas
public class Card implements Comparable{

  private int value;
  private int suit;
  public Card(int val, int s){
    value = val;
    suit = s;
  public int getValue(){
    return value;

  public int getSuit(){
    return suit;

  public void setValue(int v){
    value = v;

  public void setSuit(int s){
    suit = s;
  public int compareTo (Object rhs) {
    Card card = (Card)rhs;
    if (this.suit < card.getsuit) return -1;
    if (this.suit > card.getsuit) return  1;
    if (this.value  < card.getvalue ) return -1;
    if (this.value  > card.getvalue ) return  1;
    return 0;
  }// end of CompareTo

  public String toString() {

      StringBuffer cardDescription = new StringBuffer();
     switch(value) {
         case 14 : cardDescription.append("Ace"); break;
         case 11 : cardDescription.append("Jack"); break;
         case 12 : cardDescription.append("Queen"); break;
         case 13 : cardDescription.append("King"); break;
         default :
             cardDescription.append( value + "" );
     cardDescription.append(" of ");
     switch(suit) {
         case 1 : cardDescription.append("Clubs"); break;
         case 2 : cardDescription.append("Diamonds"); break;
         case 3 : cardDescription.append("Hearts"); break;
         case 4 : cardDescription.append("Spades"); break;
     return cardDescription.toString();

  }//end of String

****** Node Clas
public class Node {

  private Object val;
  private  Node  next;
  // Constructors.
  public Node() {
   next = null;
  public Node(Object v) {
   val = v; next = null;
  public Node(Object v, Node n) {
   val = v; next = n;  
  // Mutators.
  public void setData(Object v) {
   val = v;
  public void setNext( Node  n) {
   next = n;
  // Accessors.
  public int getData() {
   return val;
  public Node getNext() {
   return next;

****** LinkedList Clas
public class LinkedList {

  private Node head = null;
  private Node prev = null;
  private Node cur  = null;
  public boolean isEmpty() {
  return head==null;
  public boolean contains(Object v) {
  boolean found = false;
  cur  = head;
  prev = null;
  while ((cur != null) && !found) {
    if (cur.getData().compareTo(v) == 0) //generic
    found = true;
    else {
      prev = cur;
      cur  = cur.getNext();
  return found;
  public int peek() {
  return cur.getData();
   public void insert(Object v)   {
  // Insert item (v) in list between previous (prev)
  //   and current (cur) nodes.
  // Pre-conditions : cur set to node immediately after
  //                    insertion point.
  //                  prev set to node immediately prior to cur.
  //                  If inserting at head of list,
  //                    prev == null and cur == head.
  //                  If inserting at tail of list,
  //                    prev set to last node and cur == null.
  // Post-conditions: item is in list.
  //                  cur set to the new node containing item.
  //                  prev set to immediate predecessor of item.
  cur = new Node(v, cur);   // Create, fill, & assign new node.
  if (prev == null) head = cur;  // Insert at head of list
  else prev.setNext(cur);        // or insert somewhere else.

 public void remove(<type> v) {
  // Pre-conditions: None.
  if (!contains(v))
    throw new NoSuchElementException();
  cur = cur.getNext()
  if (prev == null) head = cur;
  else prev.setNext(cur);

  public void print() {
  // Pre-conditions : None.
  // Post-conditions: All elements of list displayed.
  //                  cur is unchanged.
  Node n = head;
  while (n != null) {
    n = n.getNext();

  public void clear() {
  head =prev=cur=null;
}//end of LinkedList

****** CardDeck Clas

public class CardDeck extends LinkedList {

      // instance variables
      private int numCards = 52;  //counter to keep track of the number of cards remaining in the deck
      private int idx;
      private Card[] deck;
      private LinkedList hand = new LinkedList();
      private Random generator = new Random();
      // constructor
      public void deal(Object v)
            idx = generator.nextInt(numCards) + 1;
//            hand.contains(idx)
      public void remove(Object v)
      public Object peek()

as you can see, the CardDeck class is a Linked list of the Card Class

any help please.

Card *is* an Object so you can add/remove them.
