TCP 通信多发多收

public class SocketDemo01 {
    public static void main(String[] args) {
        try {
            //1. 创建Socket通信管道请求有服务端的链接
            //public Socket(String host, int port)
            //参数一:服务端的IP地址
            //参数二:服务端的端口
            Socket socket = new Socket("127.0.0.1",9999);

            //2.从socket通信管道中得到一个字节输出流, 负责发送数据
            OutputStream os = socket.getOutputStream();

            //3.把低级的字节流包装成打印流
            PrintStream printStream = new PrintStream(os);

            Scanner sc = new Scanner(System.in);
            //4.发送消息
            while(true){
                System.out.println("请说:");
                String rs = sc.nextLine();
                printStream.println(rs);
                printStream.flush();
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
服务端

public class ACC {
    public static void main(String[] args) {
        try {
            //1.注册端口
            ServerSocket serverSocket = new ServerSocket(9999);
            //2.必须调用accept方法:  等待接受客户点的Socket连接请求, 建立Socket通信管道
            Socket socket = serverSocket.accept();
            //3.从socket通信管道中得到一个字节输入流
            InputStream is = socket.getInputStream();
            //4.把字节输入流包装成缓冲字符输入流进行消息的接收
            InputStreamReader inputStreamReader = new InputStreamReader(is);//转换流(将字节输入流转换成字符输入流)
            BufferedReader br = new BufferedReader(inputStreamReader);
            //按行读取消息
            String rs;
            while ((rs = br.readLine()) != null){
                System.out.println(socket.getRemoteSocketAddress()+"说了"+rs);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
