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

/**
