public class TcpSocket {

public static void main(String[] args) {

  try {
   //这是客户端，第一个参数是连接的ip地址，第二个参数是连接服务器的端口
   Socket socket = new Socket(InetAddress.getByName("192.168.1.101"), 8001);

//   BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
//   System.out.println(bufferedReader.readLine());
   String str = "this is really\r\n";
   //这是往服务器端发送数据
   OutputStream outputStream = socket.getOutputStream();
   outputStream.write(str.getBytes(), 0, str.getBytes().length);
   //千万注意要关闭
   outputStream.close();
   socket.close();
  } catch (Exception e) {
   e.printStackTrace();
  }

}

}

public class TcpCommunicationTest {

public static void main(String[] args) {

  ServerSocket serverSocket;
  try {
   //这是服务端,参数是等待连接的端口
   serverSocket = new ServerSocket(8001);
   //这是等待客户端来连接
   Socket socket = serverSocket.accept();
//   System.out.println("-----");
//   String senStr = "I love you\r\n";
//   socket.getOutputStream().write(senStr.getBytes(), 0, senStr.getBytes().length);
   //这是读取客户端发送的数据
   BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
   String str = br.readLine();
   System.out.println(str);
   //千万注意要关闭
   br.close();
   socket.close();
   serverSocket.close();

  } catch (Exception e) {
