java 联网版五子棋
最近学习了Java的多线程和网络编程后，利用相关知识写了一个简单的联网版五子棋小游戏，客户端和服务器就是两个玩家，实现了下棋、判断输赢和聊天的功能。
具体代码如下：
public class clientChess {
private static myFrame frame=null;
public clientChess(myFrame frame) {
this.frame=frame;
}
public void start() throws Exception{
Socket client=new Socket("192.168.43.102",10000);
final PrintWriter writer=new PrintWriter(client.getOutputStream(),true);
java.io.InputStream in=client.getInputStream();
new clientThread(client,frame).start();
//没分出胜负时，需要向服务器传棋子的坐标
Scanner sc=new Scanner(System.in);
new Thread(new Runnable() {
String line;
@Override
public void run() {
while((line=sc.nextLine())!=null) {
//frame.text.setText("我："+line);
frame.text.append("我："+line+"\r\n");
writer.println("chat:"+line);
}
}
}).start();
new Thread(new Runnable(){
@Override
public void run() {
while(!frame.isWin()) {
if(frame.backChess) {
writer.println("back:"+frame.getRow()+":"+frame.getCol());
}else {
writer.println(frame.getRow()+","+frame.getCol());
}
frame.backChess=false;
}
writer.println("win:"+frame.isWin());
}
}).start();
}
public static void main(String[] args) throws Exception {
myFrame frame=new myFrame();
clientChess client=new clientChess(frame);
client.start();
}
}
客户端线程，主要用来接收服务器发来的消息，并做出处理
class clientThread extends Thread{
Socket socket=null;
myFrame frame=null;
java.io.InputStream stream=null;
BufferedReader reader=null;
PrintWriter writer = null;
public clientThread(Socket socket,myFrame frame) {
this.socket=socket;
this.frame=frame;
try {
this.stream=this.socket.getInputStream();
this.reader=new BufferedReader(new InputStreamReader(stream));
this.writer=new PrintWriter(this.socket.getOutputStream(),true);
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void run() {
String line=null;
try {
while((line=this.reader.readLine())!=null) {
if(line.contains("ok")){
myFrame.occupy=false;
}
if(line.contains(",")) {
String[] data=line.split(",");
int row=Integer.parseInt(data[0]);
int col=Integer.parseInt(data[1]);
if(frame.chess[row][col]==0){
writer.println("ok");
frame.chess[row][col]=2;
frame.repaint();
//writer.println(frame.getRow()+","+frame.getCol());
}
}
if(line.contains("win:")) {
//System.out.println("你输了");
JOptionPane.showMessageDialog(null, "你输了");
frame.repaint();
}
if(line.contains("chat:")) {
String[] data=line.split(":");
//frame.text.setText("对方："+data[1]);
frame.text.append("对方："+data[1]+"\r\n");
}
if(line.contains("back:")) {
System.out.println(line);
String[] data=line.split(":");
int row=Integer.parseInt(data[1]);
int col=Integer.parseInt(data[2]);
frame.chess[row][col]=0;
frame.repaint();
frame.setRow(Integer.parseInt(data[1]));
frame.setCol(Integer.parseInt(data[2]));
}
}
this.socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
客户端界面：
