java应用——斗地主（二：抢地主的过程）

写代码的思路：
    1.将留下的三张地主排重新定位
    2.将每个玩家手里的牌进行排序：在将牌加入到每个玩家的链表时，就进行好排序
    3.启动三个玩家的线程，根据排序好了的卡牌重新定位
    4.进行抢地主：庄家在桌面添加组件，三个计时器（线程），抢地主的按钮。添加按钮监听器
    5.在按钮监听事件中，将底牌添加到地主手中的牌里，并进行重新定位（不抢：要做判断是将卡牌给0号玩家还是2号玩家）
    5.在桌面上添加组件：抢完地主后，在相应的地方添上地主的标志，并且在桌面上移除己方玩家的抢地主按钮，添上己方玩家出牌的按钮
    6.计时器：线程，三个倒计时框，当刚开始抢地主时，己方玩家计时器开始计时，无论按下“抢地主”还是“不抢”哪个按钮，计时器都停下计时，而当倒计时数到0时，己方不能抢地主

最开始的界面类：

package b_landTwo;import java.awt.Color;
import java.awt.Container;import javax.swing.JFrame;public class AViewJFrame extends JFrame {public static Container table;public static void main(String[] args) {new AViewJFrame().initJframe();}private void initJframe() {setSize(800, 700);setLocationRelativeTo(null);setResizable(false);setDefaultCloseOperation(1);table = getContentPane();// 绝对定位table.setLayout(null);table.setBackground(new Color(0, 112, 26));setVisible(true);// 创建一个庄家对象BBanker banker = new BBanker();banker.hold();}
}

封装的卡牌对象：

package b_landTwo;import javax.swing.ImageIcon;
import javax.swing.JLabel;public class BCards extends JLabel {private String name;// 定下协议：花色值suit 0（黑桃），1（红桃），2（梅花），3（方块）,4(大小王)// 牌面值value：0~14，表示3~10，J,Q,K,A,2,小王，大王；private int suit, value;public BCards(String name, int suit, int value) {this.name = name;this.suit = suit;this.value = value;setSize(71, 96);// 设置牌面默认为背面setIcon(new ImageIcon("images/rear.gif"));}public void overturn() {setIcon(new ImageIcon("images/" + name + ".gif"));}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getSuit() {return suit;}public void setSuit(int suit) {this.suit = suit;}public int getValue() {return value;}public void setValue(int value) {this.value = value;}}

然后的庄家：

package b_landTwo;import java.awt.Container;
import java.awt.Point;
import java.util.LinkedList;
import java.util.Random;import javax.swing.JButton;public class BBanker {public static BCards[] card = new BCards[54];// 创建一个随机数对象private Random random = new Random();// 三个玩家public BPlayer Player;/** 做庄函数*/public void hold() {for (int i = 0; i < 5; i++) {for (int j = 0; j < 13; j++) {// 准备阶段，创建54个卡牌对象，卡牌分成五堆，放在桌面上int value = j;if (i == 4 && j > 1) {break;}if (i == 4 && j < 2) {value = value + 13;}BCards cards = new BCards(i + "-" + value, i, value);cards.setLocation(300 + i * 30, 30);AViewJFrame.table.add(cards);new Thread() {public void run() {while (true) {AViewJFrame.table.repaint();try {Thread.sleep(10);} catch (InterruptedException e) {e.printStackTrace();}}};}.start();// 洗牌阶段，即每张牌随机存入数组shuffle(cards);}}// 创建三个玩家Player = new BPlayer(card);// 发牌阶段deal();// 玩家对象进行相关操作：将牌重新定位Player.operate();}/** 洗牌的函数*/private void shuffle(BCards cards) {int ran = random.nextInt(54);while (card[ran] != null) {ran = random.nextInt(54);}card[ran] = cards;}/** 发牌的函数*/private void deal() {int c = 0, f = 0, s = 0, t = 0, d = 0;for (int i = 0; i < 54; i++) {BCards cards = card[i];if (i < 51) {switch ((c++) % 3) {case 0:CMoving.move(cards, cards.getLocation(), new Point(25, 50 + (f++) * 20));int indexf = CMoving.getIndex(cards, BPlayer.linkedList0);BPlayer.linkedList0.add(indexf, cards);break;case 1:CMoving.move(cards, cards.getLocation(), new Point(137 + (s++) * 25, 550));int indexs = CMoving.getIndex(cards, BPlayer.linkedList1);BPlayer.linkedList1.add(indexs, cards);break;case 2:CMoving.move(cards, cards.getLocation(), new Point(700, 50 + (t++) * 20));int indext = CMoving.getIndex(cards, BPlayer.linkedList2);BPlayer.linkedList2.add(indext, cards);break;}cards.overturn();AViewJFrame.table.setComponentZOrder(cards, 0);} else {// 留下三张地主牌,三张地主牌重新定位cards.setLocation(280 + (d++) * 80, 30);}}}
}

庄家要用到的的移动方法：

package b_landTwo;import java.awt.Point;
import java.util.LinkedList;import javax.swing.ImageIcon;
import javax.swing.JLabel;public class CMoving {public static void move(BCards cards, Point start, Point end) {if (start.x != end.x) {// 默认向左移动int speed = -10;if (start.x < end.x) {// 向右边移动speed = -speed;}double tangent = ((double) end.y - start.y) / Math.abs(end.x - start.x);while (Math.abs(end.x - start.x) > 20) {start.x += speed;start.y += Math.abs(speed) * tangent;cards.setLocation(start.x, start.y);try {Thread.sleep(1);} catch (InterruptedException e) {e.printStackTrace();}}// 最后校准位置cards.setLocation(end);}}public static void grab(int type, int[] number, LinkedList<BCards> linkedList) {// 翻开三张底牌BBanker.card[51].overturn();BBanker.card[52].overturn();BBanker.card[53].overturn();for (int i = 0; i < 3; i++) {int adr = i + 51;int index = getIndex(BBanker.card[adr], linkedList);number[BBanker.card[adr].getValue()]++;linkedList.add(index, BBanker.card[adr]);}// 地主的标志JLabel landlord = new JLabel();landlord.setSize(40, 40);landlord.setIcon(new ImageIcon("images/dizhu.gif"));// 重新定位for (int i = 0; i < linkedList.size(); i++) {BCards cards = linkedList.get(i);switch (type) {case 0:CMoving.move(cards, cards.getLocation(), new Point(27, 50 + i * 20));landlord.setLocation(120, 200);break;case 1:CMoving.move(cards, cards.getLocation(), new Point(137 + i * 25, 550));landlord.setLocation(315, 470);break;case 2:CMoving.move(cards, cards.getLocation(), new Point(698, 50 + i * 20));landlord.setLocation(615, 200);break;}AViewJFrame.table.setComponentZOrder(cards, 0);AViewJFrame.table.add(landlord);}}/** 获取插入到链表位置的索引*/public static int getIndex(BCards cards, LinkedList<BCards> linkedList) {for (int i = 0; i < linkedList.size(); i++) {BCards bCards = linkedList.get(i);if (cards.getValue() > bCards.getValue()) {return i;}}return linkedList.size();}
}

庄家之后是玩家：

package b_landTwo;import java.awt.Color;
import java.awt.Container;
import java.awt.Point;import java.util.LinkedList;import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JTextField;/** 一个类三个玩家对象，三个玩家类对象共同有的功能：* 1.将手中的牌排序，2.分析牌型和拆牌*/
public class BPlayer {public BCards[] card;// 一个玩家一个链表放卡牌public static LinkedList<BCards> linkedList0 = new LinkedList<>();public static LinkedList<BCards> linkedList1 = new LinkedList<>();public static LinkedList<BCards> linkedList2 = new LinkedList<>();// 一个玩家一个数组计算手中的各点数牌的排数public static int[] number0 = new int[15];public static int[] number1 = new int[15];public static int[] number2 = new int[15];// 三个计时器public static JTextField[] jText = new JTextField[3];// 按钮public static JButton jBloot, jblnot;public BPlayer(BCards[] card) {this.card = card;}public void operate() {// 将排序好了的（没考虑花色）卡牌重新定位rank(0, linkedList0);rank(1, linkedList1);rank(2, linkedList2);// 清算每个玩家手中的卡牌liquad(number0, linkedList0);liquad(number1, linkedList1);liquad(number2, linkedList2);// 叫地主grab();BTimer bTimer = new BTimer();bTimer.start();// 玩家之间进行出牌的游戏，地主先出牌JButton jBplay = new JButton("出牌");JButton jbpass = new JButton("不要");jBplay.setBounds(280, 520, 80, 20);jbpass.setBounds(431, 520, 80, 20);CButListener cButListener = new CButListener();jBplay.addActionListener(cButListener);jbpass.addActionListener(cButListener);AViewJFrame.table.add(jBplay);AViewJFrame.table.add(jbpass);}/** 排序的函数*/private void rank(int type, LinkedList<BCards> linkedList) {for (int i = 0; i < linkedList.size(); i++) {BCards cards = linkedList.get(i);switch (type) {case 0:CMoving.move(cards, cards.getLocation(), new Point(30, 50 + i * 20));break;case 1:CMoving.move(cards, cards.getLocation(), new Point(137 + i * 25, 550));break;case 2:CMoving.move(cards, cards.getLocation(), new Point(695, 50 + i * 20));break;}AViewJFrame.table.setComponentZOrder(cards, 0);}}/** 清算卡牌的函数*/private void liquad(int[] number, LinkedList<BCards> linkedList) {for (int i = 0; i < linkedList.size(); i++) {BCards cards = linkedList.get(i);int value = cards.getValue();number[value]++;}}/** 抢地主的函数*/private void grab() {// 添加三个线程计时器for (int i = 0; i < 3; i++) {jText[i] = new JTextField("倒计时：");AViewJFrame.table.add(jText[i]);}jText[0].setBounds(120, 250, 60, 40);jText[1].setBounds(365, 470, 60, 40);jText[2].setBounds(615, 250, 60, 40);// 抢地主的按钮jBloot = new JButton("抢地主");jblnot = new JButton("不抢");jBloot.setBounds(280, 520, 80, 20);jblnot.setBounds(431, 520, 80, 20);CButListener cButListener = new CButListener();jBloot.addActionListener(cButListener);jblnot.addActionListener(cButListener);AViewJFrame.table.add(jBloot);AViewJFrame.table.add(jblnot);}
}

玩家抢地主要用到监听器：

package b_landTwo;import java.awt.Container;
import java.awt.Point;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.LinkedList;import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JLabel;public class CButListener implements ActionListener {public static boolean cont = true;public void actionPerformed(ActionEvent e) {String command = e.getActionCommand();if ("抢地主".equals(command)) {// 将三张底牌加入己方的卡牌，重新进行洗牌和定位CMoving.grab(1, BPlayer.number1, BPlayer.linkedList1);BPlayer.jText[1].setText("stop");cont = false;AViewJFrame.table.remove(BPlayer.jBloot);AViewJFrame.table.remove(BPlayer.jblnot);} else if ("不抢".equals(command)) {// 将三张底牌加到王和2的卡牌数量多的一方玩家手中，如果数量相同，默认加到0号玩家int player0 = BPlayer.number0[12] + BPlayer.number0[13] + BPlayer.number0[14];int player2 = BPlayer.number2[12] + BPlayer.number2[13] + BPlayer.number2[14];if (player0 >= player2) {CMoving.grab(0, BPlayer.number0, BPlayer.linkedList0);} else {CMoving.grab(2, BPlayer.number2, BPlayer.linkedList2);}BPlayer.jText[1].setText("stop");cont = false;AViewJFrame.table.remove(BPlayer.jBloot);AViewJFrame.table.remove(BPlayer.jblnot);}else if ("出牌".equals(command)) {} else if ("不要".equals(command)) {}}
}

还有三个计时器，是用的线程：

package b_landTwo;import java.awt.Container;public class BTimer extends Thread {private int time = 15;public void run() {while (time > 0 && CButListener.cont) {BPlayer.jText[1].setText("倒计时:" + (time--));try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}if (CButListener.cont) {BPlayer.jText[1].setText("stop");AViewJFrame.table.remove(BPlayer.jBloot);AViewJFrame.table.remove(BPlayer.jblnot);// 将三张底牌加到王和2的卡牌数量多的一方玩家手中，如果数量相同，默认加到0号玩家int player0 = BPlayer.number0[12] + BPlayer.number0[13] + BPlayer.number0[14];int player2 = BPlayer.number2[12] + BPlayer.number2[13] + BPlayer.number2[14];if (player0 >= player2) {CMoving.grab(0, BPlayer.number0, BPlayer.linkedList0);} else {CMoving.grab(2, BPlayer.number2, BPlayer.linkedList2);}}}
}

不足：
    1.刚开始发牌时，窗体的加载和庄家类的发牌好像都要抢占窗体对象，感觉卡顿（已经解决，解决方案：将桌面放在静态块）
    2.代码运行时有时会抛出空指针异常，有时不会抛，我没找到哪行代码出了问题
    3.没有解决好三张底牌翻开时应该在桌面上停一会的需求，加了单线程睡眠也没用。
    4.没有处理好类与类之间的关系，有很多重复的代码

最后是运行的结果图：
