hand.java

Java Classic Examples是我买的两本书：《JAVA经典实例》和《java入门经典源代码》里边附送光盘里带的源码

// Class defining a hand of cards
import java.util.*;

class Hand
{
  public void add(Card card)
  {
    hand.push(card);
  }

  public String toString()
  {
    Iterator cards = hand.iterator();

    StringBuffer str = new StringBuffer();
    while(cards.hasNext())
      str.append(" "+ (Card)cards.next());
    return str.toString();
  }
    
  private Stack hand = new Stack();       // Stores the cards in the hand
}
