Java IO 流分为输入流InputStream和输出流OutputStream

输入流输出流

InputStreamOutputStream

读进来写出去

读到程序内存写出到流里面

1、客户端

public static void main(String[] args) throws IOException { new Thread(() -> { Socket socket = null; try { socket = new Socket("", 3333); } catch (IOException e) { e.printStackTrace(); } try { while (true) { OutputStream outputStream = socket.getOutputStream(); String format = DateFormat.getDateTimeInstance().format(new Date()); outputStream.write((format + " hello world!").getBytes()); Thread.sleep(2000); } } catch (Exception e) { } }).start(); }2、服务端
