本文实例为大家分享了Java实现五子棋网络版的具体代码，供大家参考，具体内容如下
需求分析：
对于网络五子棋而言，在普通五子棋的基础上需要添加以下功能：
1.拥有服务器端和客户端，用户通过客户端登录服务器后可与其他登录的用户进行对弈
2.服务器支持多组用户同时进行对弈
3.用户可以在服务器上创建新游戏或加入已创建的游戏
4.用户在下棋的时候可以进行聊天交流
由上可以知道需要实现的功能：
・提供服务器和客户端的功能
・服务器将监听客户端的登录情况并允许多个客户端进行登录
・用户通过客户端可以登录服务器，之后可以看到服务器当前在线的其他用户，并与他们进行聊天等
・用户登录服务器后，可以创建新的五子棋游戏或加入已创建的五子棋游戏
・用户通过客户端可以像普通五子棋那样与其他用户对弈
根据功能将网络五子棋分为4个模块：即用户面板模块、棋盘面板模块、五子棋服务器模块、五子棋客户端模块
下面我们开始进行编译用户面板模块：
1.开发用户列表面板
import java.awt.*; /** * Created by Administrator on 2016/11/21. */ //初始状态下将添加10个名称为“无用户“的信息到列表中，说明服务器最多支持10个用户同时在线 //该列表被添加到面板中，使用“BorderLayout”布局格式 public class UserListPad extends Panel{ public List userList=new List(10); public UserListPad(){ setLayout(new BorderLayout()); for(int i=0;i<10;i++){ userList.add(i+"."+"无用户"); } add(userList,BorderLayout.CENTER); } } 2.开发用户聊天面板
import javax.swing.*; import java.awt.*; /** * Created by Administrator on 2016/11/21. */ //聊天面板为一个TextArea视图控件，拥有一个垂直方向的滚动条。 //该TextArea被添加到面板中，使用“BorderLayout”布局格式。 public class UserChatPad extends JPanel{ public JTextArea chatTextArea=new JTextArea("命令区域",18,20); public UserChatPad(){ setLayout(new BorderLayout()); chatTextArea.setAutoscrolls(true); chatTextArea.setLineWrap(true); add(chatTextArea,BorderLayout.CENTER); } } 3.开发用户输入面板
import javax.swing.*; import java.awt.*; /** * Created by Administrator on 2016/11/21. */ //面板包含两个视图控件 //contentInpitted为TextField控件，用户可以在其中输入聊天信息 public class UserInputPad extends JPanel{ public JTextField contentInputted = new JTextField("",26); public JComboBox userChoice = new JComboBox(); public UserInputPad(){ setLayout(new FlowLayout(FlowLayout.LEFT)); for(int i=0;i<50;i++){ userChoice.addItem(i+"."+"无用户"); } userChoice.setSize(60,24); add(userChoice); add(contentInputted); } } 4.开发用户操作面板
import javax.swing.*; import java.awt.*; /** * Created by Administrator on 2016/11/21. */ public class UserControlPad extends JPanel { public JLabel ipLabel = new JLabel("IP",JLabel.LEFT); public JTextField ipInputted = new JTextField("localhost",10); public JButton connectButton = new JButton("连接到服务器"); public JButton createButton = new JButton("创建游戏"); public JButton joinButton = new JButton("加入游戏"); public JButton cancelButton = new JButton("放弃游戏"); public JButton exitButton = new JButton("退出游戏"); public UserControlPad(){ setLayout(new FlowLayout(FlowLayout.LEFT)); setBackground(Color.LIGHT_GRAY); add(ipLabel); add(ipInputted); add(connectButton); add(createButton); add(joinButton); add(cancelButton); add(exitButton); } } 下面开始开发棋盘面板模块
1.开发黑棋类
import java.awt.*; /** * Created by Administrator on 2016/11/21. */ public class FIRPointBlack extends Canvas { FIRPad padBelonged; // 黑棋所属的棋盘 public FIRPointBlack(FIRPad padBelonged) { setSize(20, 20); // 设置棋子大小 this.padBelonged = padBelonged; } public void paint(Graphics g) { // 画棋子 g.setColor(Color.black); g.fillOval(0, 0, 14, 14); } } 2.开发白棋类
import java.awt.*; /** * Created by Administrator on 2016/11/21. */ public class FIRPointWhite extends Canvas{ FIRPad padBelonged; // 白棋所属的棋盘 public FIRPointWhite(FIRPad padBelonged) { setSize(20, 20); this.padBelonged = padBelonged; } public void paint(Graphics g) { // 画棋子 g.setColor(Color.white); g.fillOval(0, 0, 14, 14); } } 3.开发棋盘面板
import java.awt.*; import java.awt.event.*; import java.io.*; import java.net.*; import javax.swing.JTextField; /** * Created by Administrator on 2016/11/21. */ public class FIRPad extends Panel implements MouseListener,ActionListener{ // 鼠标是否能使用 public boolean isMouseEnabled = false;
