Tcp客户服务器模式通信

Client客户端，实现的任务是发送数据给服务器，然后还可以接收并输出服务器传回的数据。

public class tcpClient {

    public static void main(String[] args) throws UnknownHostException, IOException {
        // TODO Auto-generated method stub
        Socket socket = new Socket(InetAddress.getByName("10.0.185.54"),11111);

        System.out.println("客户端启动...");

        OutputStream out = socket.getOutputStream();

        out.write("hello,Im tom".getBytes());

        InputStream in = socket.getInputStream();
        byte[] arr = new byte[1024];
        int len = in.read(arr);

        System.out.println(new String(arr,0,len));

        in.close();
        out.close();
        socket.close();

    }

}

Server服务器端，实现的任务是接收客户端发送的数据并返回信息。

public class tcpServer {

    public static void main(String[] args) throws IOException {
        // TODO Auto-generated method stub
        ServerSocket server = new ServerSocket(11111);

        Socket socket = server.accept();

        InputStream in = socket.getInputStream();

        byte [] arr = new byte[1024];
        int len = in.read(arr);

        System.out.println(new String(arr,0,len));

        OutputStream out = socket.getOutputStream();
        out.write("收到".getBytes());

        out.close();
        in.close();
        socket.close();

    }

}
