my question is:
the socket opened by client is closed by closing the InputStream associated
to it?
in other words, should I do socket.close() instead of in.close() in the
finally block?
Thanks!
public class DaytimeApplet extends Applet {
......
private String getDateUsingSocketText() {
InputStream in = null;
try {
// Establish a socket connection with the servlet
Socket socket = new Socket(getCodeBase().getHost(), getSocketPort());
// Print an empty line, indicating we want the time as plain text
PrintStream out = new PrintStream(socket.getOutputStream());
out.println();
out.flush();
// Read the first line of the response
// It should contain the current time
in = socket.getInputStream();
DataInputStream result =
new DataInputStream(new BufferedInputStream(in));
String date = result.readLine();
// Return the retrieved string
return date;
}
catch (Exception e) {
// If there was a problem, print to System.out
// (typically the Java console) and return null
e.printStackTrace();
return null;
}
finally {
// Always close the connection
// This code executes no matter how the try block completes
if (in != null) {
try { in.close(); }
catch (IOException ignored) { }
}
}
}
