JAVA学习面向对象之 扑克牌（初）

标签：

感想：

      一开始不了解或者说是对JAVA的特性不熟悉，不知道类与类之间的联系，对JAVA的封装，继承，多态不熟悉和没有更好的理解，在以后的学习过程中要掌握并熟悉JAVA的开发习惯，

在写代码过程中还有众多东西没有掌握，靠着老师和同学的帮助完成这次学习，初步了解了JAVA面向对象开发的基本要领。写这个博客以便于自己今后学习，也算是一段美好的回忆吧！

上面是一个类图  表示着写这个程序的只要思路。

Card类:他的下级是cardview上级是player,有着一定的关系

package com.cqvie;
public class Card
{
  public int rank,suit;
  public int cardIdx;
  public CardView cardView;
  public Player owner;
  public boolean selected=false;
  public static String suits[]
                             =new String[]{"","♠","♥","♣","♦"};
  public static String ranks[]
                             =new String[]{"J","Q","K","A","2","小王","大王"};
 
  public Card(int rank,int suit)
  {
    this.rank=rank;  this.suit=suit;
    this.cardView=new CardView(this); //在产生Card对象时，要同步产生CardView对象
  }
  public String toString()
  {
   if(rank<=10) //10点或以下
    return suits[suit]+rank;
   else //10点以上
    return suits[suit]+ ranks[rank-11];
  }
}

CardView类：

package com.cqvie;

import java.awt.Font;
import java.awt.Insets;
import java.awt.Panel;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.JButton;
import javax.swing.JFrame;

public class CardView {
 private Card card; // 关联的Card
 private JButton btn;
 //private static JFrame win; // 依附的窗口
 
 public Card getCard() {
  return card;
 }

 public void setCard(Card card) {
  this.card = card;
 }

 public JButton getBtn() {
  return btn;
 }

 public void setBtn(JButton btn) {
  this.btn = btn;
 }

 public CardView(final Card card) {
  this.card = card;
  btn = new JButton();
  btn.setSize(50, 80);
  btn.setMargin(new Insets(0, 0, 0, 0)); //文字和控件的边距
  btn.setFont(new Font(btn.getFont().getName(), Font.BOLD, 16)); //字体设置
  btn.addMouseListener(new MouseAdapter() {

   @Override
   public void mouseClicked(MouseEvent e) {
    System.out.println(card.toString());
    card.selected=!card.selected;
    JButton b=(JButton)e.getSource();
    if(card.selected) b.setLocation(b.getX(),b.getY()-20);
    else b.setLocation(b.getX(),b.getY()+20);
   }
   
  });
 }

 public void show()
 {
  btn.setText(card.toString());
  int x=card.cardIdx*btn.getWidth()+50;
  //y=card.owner.payerIdx*150+50;
  btn.setLocation(x,20);
  this.card.owner.playerView.panel.add(btn);
 }
 
 public void refresh() //刷新按钮位置
 {
  int x=card.cardIdx*btn.getWidth()+50;
  btn.setLocation(x,20);  
 }
}

Player类：

package com.cqvie;

import java.util.Collections;
import java.util.Comparator;
import java.util.LinkedList;
import java.util.List;

public class Player {
 //public String id;
 public int payerIdx;
 public boolean isLandlord;
 public List<Card> cards;
 public PlayerView playerView;
 public Player(int payerIdx)
 {
  this.payerIdx=payerIdx;
  isLandlord=false;
  cards=new LinkedList<Card>();
  this.playerView=new PlayerView(this);
 }
 
 public void putCards() //出牌
 {
  for(int i=cards.size()-1;i>=0;i--)
   if(cards.get(i).selected)
   {
    //从cards集合中删除card对象
    Card c= cards.remove(i);
    this.playerView.panel.remove(c.cardView.getBtn());
    //c.cardView.getBtn().setVisible(false);
   }
  //出牌后调整按钮位置
  for(int i=0;i<cards.size();i++) //更新cardIdx
  {
   cards.get(i).cardIdx=i;
   cards.get(i).cardView.refresh();
  }
  this.playerView.panel.repaint(); //刷新面板
 } 
 
 public void sortCards() //排序
 {
  Collections.sort(cards,new CardComparetor());
  for(int i=0;i<cards.size();i++) //更新cardIdx
   cards.get(i).cardIdx=i;
 }
}

class CardComparetor implements Comparator<Card>
{
 @Override
 public int compare(Card o1, Card o2) {
  if(o1.rank!=o2.rank) return o2.rank-o1.rank;
  else return o1.suit-o2.suit;
 } 
}

PlayerView类:

public class PlayerView {
 public Player player;
 public JPanel panel;
 
 public PlayerView(Player p)
 {
  this.player=p;
  panel=new JPanel();
  panel.setLayout(null); //绝对布局
  panel.setSize(1300, 160);
  panel.setBackground(new Color(255, 255, 0));
 }
 
 public void show()
 {
  panel.setLocation(50, (panel.getHeight()+5)*player.payerIdx);
  GameManager.win.add(panel);
  for(int i=0;i<this.player.cards.size();i++)
   this.player.cards.get(i).cardView.show();
  //显示玩家信息
  JLabel label=new JLabel();
  label.setSize(100,50);
  label.setLocation(50, 100);
  label.setText("玩家"+(this.player.payerIdx+1));
  panel.add(label);
  //添加“出牌”按钮
  JButton b=new JButton();
  b.setSize(80,40);
  b.setLocation(150, 120);
  b.setText("出牌");
  panel.add(b);
  b.addMouseListener(
    new MouseAdapter() {

     @Override
     public void mouseClicked(MouseEvent e) {
      player.putCards(); //player是外部类的属性
     }

  for(int i=0;i<players.length;i++)
   players[i]=new Player(i);
 }
 public void startGame()
 {
  List<Card> cards=new LinkedList<Card>(); //扑克牌
  for(int i=3;i<=15;i++)
   for(int j=1;j<=4;j++)
    cards.add(new Card(i,j));
  
  cards.add(new Card(16,0));
  cards.add(new Card(17,0));
  
  Random r=new Random(); //随机数产生器
  for(int i=0;i<players.length;i++)
  {
   for(int j=0;j<17;j++)
   {
    int k=r.nextInt(cards.size());
    cards.get(k).owner=players[i];

    cards.remove(k);
   }
   players[i].sortCards();
  }
  
     int t = (int)(Math.random() *players.length);
  players[t].isLandlord=true; 
  if(players[t].isLandlord)
    for(int m=17;m<=19;m++){
             int k = (int)(Math.random() * cards.size());
             cards.get(k).owner=players[t];
             cards.get(k).cardIdx=m;
             players[t].cards.add(cards.get(k));
             cards.remove(k);
   }
  players[t].sortCards();
  
//  for(int i=0;i<players.length;i++)
//  {
//   System.out.print(players[i].id+players[i].isLandlord+"的牌是");
//   players[i].cards.print();
//   System.out.print("\n------------------------\n");
//  }
 }
 
 public void show()
 {
//  for(int i=0;i<players.length;i++)
//   for(int j=0;j<players[i].cards.size();j++)
//   {
//    players[i].cards.get(j).cardView.show();

 }

}

Test类：
