基于 socket 的联网五子棋，这个项目是我用来参加十二届的易途杯和团队一起写的，虽然没有获奖（其他队伍太强了！！！！）
项目特点
1 . 基于 socket 实现了联网状态下的五子棋
2 . 使用 Graphics 实现棋盘的绘制和棋子的绘制
3 . 实现了五子棋的基本功能
项目缺点
1 . 没有实现悔棋的功能
2 . 用户界面不够美观，用户体验感不好
3 . 没有采用多线程（不会啊！）

下面就直接附上代码和运行截图吧，至于具体代码的解释等以后再进行更新吧，有不懂的可以在下面评论留言，看到会回复的！

运行界面

下面就直接给出代码吧！

判断是否胜利

初始化棋盘

package jobangfinaly;public class CLearChess {JframeDemo jDemo =null;public CLearChess(JframeDemo jframeDemo) {this.jDemo=jframeDemo;}public void clearChess() {// 初始化棋盘for (int i = 0; i < 12; i++) {for (int j = 0; j < 12; j++) {jDemo.chess[i][j] = 0;}}jDemo.me = true;// 初始化为己方落黑子jDemo.repaint();}
}

绘制棋子

package jobangfinaly;import java.awt.Color;
import java.awt.Graphics;public class DrawChess {public void drawChess(Graphics g) {JframeDemo jDemo = new JframeDemo();for (int i = 0; i < 12; i++) {for (int j = 0; j < 12; j++) {if (jDemo.chess[i][j] == 1) {g.setColor(Color.black);g.fillOval((i + 1) * 50 - 19, (j + 1) * 50 - 19, 38, 38);} else if (jDemo.chess[i][j] == 2) {g.setColor(Color.white);g.fillOval((i + 1) * 50 - 19, (j + 1) * 50 - 19, 38, 38);} else if (jDemo.chess[i][j] == 11) {// 点击落黑子时外加个黑框g.setColor(Color.black);g.fillOval((i + 1) * 50 - 19, (j + 1) * 50 - 19, 38, 38);g.drawRect((i + 1) * 50 - 19, (j + 1) * 50 - 19, 38, 38);} else if (jDemo.chess[i][j] == 22) {// 点击落白子时棋子外加个白框g.setColor(Color.white);g.fillOval((i + 1) * 50 - 19, (j + 1) * 50 - 19, 38, 38);g.drawRect((i + 1) * 50 - 19, (j + 1) * 50 - 19, 38, 38);}}}}}

绘制棋盘

package jobangfinaly;import java.awt.Color;
import java.awt.Graphics;public class DrawChessBoard {public void drawChessBoard(Graphics g) {// 画棋盘for (int i = 50; i <= 600; i += 50) {g.setColor(Color.WHITE);g.drawLine(i, 50, i, 600);g.drawLine(50, i, 600, i);}}}

接受数据

package jobangfinaly;import java.io.IOException;
import java.io.InputStream;
import java.net.ServerSocket;
import java.net.Socket;import javax.swing.JOptionPane;public class Receive {JframeDemo jDemo =null;public Receive(JframeDemo jDemo) {this.jDemo = jDemo;}public void receive() {// 服务端接收对方发来的坐标ChangeChess doit = new ChangeChess(jDemo);CheckWiner checkWiner = new CheckWiner(jDemo);ServerSocket serverSocket = null;try {serverSocket = new ServerSocket(jDemo.clientPort);} catch (IOException e) {e.printStackTrace();}// 从该端口接收数据while (true) {Socket sSocket = null;try {sSocket = serverSocket.accept();} catch (IOException e) {e.printStackTrace();}InputStream is = null;try {is = sSocket.getInputStream();} catch (IOException e) {e.printStackTrace();}byte[] bys = new byte[1024];int len = 0;try {len = is.read(bys);} catch (IOException e) {e.printStackTrace();}String strReceive = new String(bys, 0, len);String[] strs = strReceive.split("-");// 使用"-"分割字符串,得到坐标jDemo.ex = Integer.parseInt(strs[0]);jDemo.ey = Integer.parseInt(strs[1]);doit.doit();// 落子checkWiner.checkWiner();jDemo.one = true;// 变为己方落子}}}

发送坐标

package jobangfinaly;import java.io.OutputStream;
import java.net.Socket;import javax.swing.JOptionPane;public class Send {JframeDemo jDemo = null;public Send(JframeDemo jDemo) {super();this.jDemo = jDemo;}public void sendXY(int xSend, int ySend) {// 传送鼠标点击的坐标        try {// 问题在于每次传送坐标都要重新创建一个socket对象,不知道怎么改进Socket socket = new Socket(jDemo.inetAddress, jDemo.serverPort);// 设置对方服务器端IP,并设置端口号为9653;OutputStream os = socket.getOutputStream();String strr = xSend + "-" + ySend;// 使用-符号连接坐标,并以字符串形式发送到服务端os.write(strr.getBytes());socket.shutdownOutput();// 及时发送位置信息,不用closs()是保持通信一直连接} catch (Exception ex) {JOptionPane.showMessageDialog(null, "您的网络连接错误！", "网络错误", JOptionPane.ERROR_MESSAGE);System.exit(0);ex.printStackTrace();}}}

这次的易途杯比赛浪费了好多时间，而且最后也没有获奖，团队里就两个人在努力，害，下次做项目的话，一定要找好团队，确定具体的计划，确定好具体的分工，写好项目思路，写好项目报告，好好学习基础知识，不会的地方要搞明白，还有PPT的制作，一定要有，这是一个加分项，不止是加分项还是一个项目演示的基本思路，害，总之还是自己太菜了，下次继续加油吧！！！！！！！！！！！！
