TCP通信程序练习3——服务器数据写入文件

客户端代码:

public class ClientDemo {
    public static void main(String[] args) throws IOException {
        //创建客户端Socket对象
        Socket s = new Socket("192.168.50.76",11111);

        //获取输入流，数据来自于键盘录入，直到输入的是886，发送数据结束
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
        String line;
        while ((line=br.readLine())!=null){
            if (line.equals("886")){
                break;
            }
            //发送数据
            bw.write(line);
            bw.newLine();
            bw.flush();
        }
        //释放资源
        s.close();
    }
}

服务器端代码：

public class ServerDemo {
    public static void main(String[] args) throws IOException {
        //创建客户端Socket对象
        ServerSocket ss = new ServerSocket(11111);

        //监听客户端连接
        Socket s = ss.accept();

        //接收数据
        BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));

        //把数据写入文本文件
        BufferedWriter bw = new BufferedWriter(new FileWriter("myNet\\bw.txt"));
        String line;
        while ((line=br.readLine())!=null){
            bw.write(line);
            bw.newLine();
            bw.flush();
        }

        //释放资源
        ss.close();
        bw.close();

    }
}

运行结果：
