Java Array Index Out of Bounds somehow?

In my game's code, I am trying to add a card to hand. As soon as I do, my array is out of bounds. Everything looks right, but maybe I'm missing something.

FYI, one and two are Player instances. Relevant code from Main class (sorry about the formatting. i suck at transferring it to Stack Overflow):

        Scanner scan = new Scanner(System.in);
        String something = "yes", something2 = "yes"; //Use with while loop
        String winner = "yes"; //Use for while loop
        String temp; //Use with setting names
        Card[] deck = new Card[52]; //Deck array
        int playercount = 0;

        Player three = new Player("temp");
        Player four = new Player("temp");

        while (something2.equals("yes") || playercount < 2) {  //Add players to game

            System.out.println("Would a(nother) player like to join?");

Player class:

import java.util.*;

    private Card[] hand = new Card[52];
    private int handsize = 0; 

    //Constructor
    public Player(String n) {

    }

    //Mutators
    public void addCard(Card c) {
        hand[handsize] = c;
        handsize++;
    }

    //Accessors
    public String getName() {
        return name;   
    }
    public Card[] getHand() {
        return hand;   
    }
}

回答1:

The problem is with your loop

while (something.equals("yes"))

There's nothing that sets something to any other value, so this loop just goes around endlessly, until all the players have more than 52 cards. Once someone has more than 52 cards, adding a new card causes the exception.

I think you need to remove this while. The code inside it should only be run once.

回答2:

Your draw method is broken.

// get the first non-null Card from the cards "c".
public static Card draw(Card[] c) {
  if (c != null) {
    for (int i = 0; i < c.length; i++) {
      if (c[i] != null) {
        try {
          return c[i];
        } finally {
          // now remove element i from the `c` array.
          c[i] = null;
        }
      }
    }
  }
  return null;
}

回答3:

I think the order of your code is incorrect (hard to tell with this code)

for (int i = 1; i < 8; i++)
{
 one.addCard(Card.draw(deck));
 deck = Card.getDeck();
 two.addCard(Card.draw(deck));
 deck = Card.getDeck();
}

maybe should be

for (int i = 1; i < 8; i++)
{
 deck = Card.getDeck();
 one.addCard(Card.draw(deck));
 deck = Card.getDeck();
 two.addCard(Card.draw(deck));
}

Update

Also

public void addCard(Card c) {
    hand[handsize] = c;
    handsize++;
}

handsize is never incremented - it is always 0
