For example

• The following code fragment connects to the daytime server on port 13 of metalab.unc.edu, and displays the data it sends.

try {
  Socket s = new Socket("metalab.unc.edu", 13);
  InputStream in = s.getInputStream();
  InputStreamReader isr = new InputStreamReader(in);
  BufferedReader br = new BufferedReader(isr);
  String theTime = br.readLine();
  System.out.println(theTime);
}
catch (IOException e) {
  return (new Date()).toString();
}
