Need help with this program please! The classes are related so I have no choice but to post all sub questions for this program. If you can include comments as much as possible for better understanding that would be great.

Im not sure if number 4 is related to the first 3 parts, if it isint then discard it no need to answer that part! thanks will upvote!

CARD CLASS:

* Jack = 11, Queen = 12, King = 13, Ace = 14

HAND CLASS:

import java.util.List;

public class Hand{ protected List cards; public Hand(List cards){ this.cards = cards; } public int numberOfCards(){ if( this.cards == null ){ return -1; }else{ return this.cards.size(); } } public List getCards(){ return this.cards; } /* remove and return the specified card from the hand */ /* return null if the card is not in the hand */ public Card remove(Card card){return new StandardCard(Card.SUITS[4], Card.RANKS[1]);} /* add the specified card to the hand */ public void add(Card card){} }

DECK CLASS:

import java.util.List;

/* finish all of the constructors and methods given here */

/* do NOT add any public attributes or methods */

/* add any protected/private attributes you need */

public class Deck{

public Deck(){}

public Deck(int nun_jokers){}

public List getCards(int num_cards){return null;}

public Card getCard(){return null;}

public void addCard(Card c){}

}

PLAYER CLASS: **THIS IS FOR NUMBER 4 IF IT IS RELATED TO THE PREVIOUS 3**

public abstract class Player{ protected Hand hand; public Player(Hand hand){ this.hand = hand; } /* play a card from the player's hand */ /* returns null if they cannot play a card and the deck becomes empty */ /* do NOT return null unless you cannot play a card and the deck is empty */ public abstract Card play(Card top_of_discard_pile, Deck deck); public final int cardsLeft(){ return this.hand.numberOfCards(); } }

A standard deck of playing cards consists of 52 cards. Each card has a rank (2, 3, . 9, 10, Jack Queen, King, or Ace) and a suit (spades *, hearts V, clubs *, or diamonds) You will create a class called StandardCard that will simulate cards from a standard deck of cards. Your class will extend the Card class (provided) The ordering of the cards in a standard deck(as defined for this assignment) is first specified by the suit and then by rank if the suits are the same. The suits and ranks are ordered as follows: suits: The suits will be ordered diamonds ?
