如何连接以下链接中显示的2个java类客户端服务器:

它说我需要使用TCPserver进行编译,我已经尝试在我的IDE中找到编译选项,即Netbeans,但我似乎无法在任何地方找到它。我可以请一些关于如何连接这两个文件的提示,以便服务器文件响应客户端应用程序吗?

首先,您需要启动服务器(Serversocket),它将等待客户端套接字连接。

ServerSocket serverSocket = new ServerSocket(PORT);
Socket socket = serverSocket.accept();
ObjectInputStream objectInputStream = new ObjectInputStream(socket.getInputStream());
try {
      Object object = objectInputStream.readObject();
      System.out.println("read by the server\t" + object);
      ObjectOutputStream objectOutputStream = new ObjectOutputStream(socket.getOutputStream());
      objectOutputStream.writeObject("this is message by the server");
   }catch(Excetion e) {
    e.printStackTrace();
   }

serversocket接受,而OIS的readObject()方法将阻塞该线程,因此你必须启动一个新线程。

创建套接字对象时,客户端将连接。之后,您可以通过流发送和接收双方的消息。

// host is the localhost IP
Socket socket = new Socket(host, PORT);
ObjectOutputStream objectOutputStream = new ObjectOutputStream(socket.getOutputStream());
objectOutputStream.writeObject("this is the message by the client");
ObjectInputStream objectInputStream = new ObjectInputStream(socket.getInputStream());
try {
    System.out.println("read by the client\t" + objectInputStream.readObject());
    }catch(Excetion e) {
    e.printStackTrace();
    }
