duration

问题 I want to use a JFormattedTextField to allow the user to input time duration values into a form. Sample valid values are: 2h 30m 72h 15m 6h 0h However I am having limited success with this.

If it is worth anything, here\'s my current attempt: mFormattedText.setFormatterFactory( new DefaultFormatterFactory( new DateFormatter( new SimpleDateFormat(\"H mm\"))));

" / Dimensions: ".$file['video']['resolution_x']." wide by ".$file['video']['resolution_y']." tall". " / Filesize: ".
