Socket的简单使用

public void yesIo() throws IOException {
    System.out.println("socket监听10086");
    new Thread(() -> {
        //创建一个10086端口的监听器
        ServerSocket serverSocket = null;
        try {
            serverSocket = new ServerSocket(10086);
   
            Socket clientSocket = serverSocket.accept();
            BufferedReader in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
            PrintWriter out = new PrintWriter(clientSocket.getOutputStream());
            String request, response;
            while ((request = in.readLine()) != null) {
                if ("done".equals(request)) {
                    break;
                }
                System.out.println(request);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }).run();
   
   
}

System.out.println("启动客户端");
String ip = "localhost";
Socket socket = new Socket(ip, 10086);
Writer writer = new OutputStreamWriter(socket.getOutputStream());
writer.write("Hello From Client");
writer.flush();
writer.close();
