Description

I haven't seen any public utilities out there that can display an elapsed time
in a human readable form. I figured if it doesn't already exist in the commons,
it would be useful for others. I'm not sure what package it would go in
(StringUtil or NumberUtil maybe?). Anyway, here's a little public static method
that I use to get a readable elapsed time display for a time in milliseconds.
Not that this is rocket science, but I found the guts of the code on some public
forum.

---------------------------
/**

• Formats an elapsed time in milliseconds to a more human-readable form.
• Output is in the format hh:mm:ss
• @param elapsedMillis time in milliseconds.
• @return the amount of time in hh:mm:ss format.
  */
  public static String formatTime(long elapsedMillis) { // first turn the amount in millis to be seconds...it's easier to format the hhmmss that way. long elapsedSeconds = elapsedMillis / 1000; long formattedHours = elapsedSeconds / 3600; long formattedMinutes = (elapsedSeconds % 3600) / 60; long formattedSeconds = elapsedSeconds % 60; // if you also want formatted milliseconds, here's how... // long formattedMillis = elapsedMillis % 1000; return ((formattedHours < 10 ? "0" : "") + formattedHours + ":" + (formattedMinutes < 10 ? "0" : "") + formattedMinutes + ":" + (formattedSeconds < 10 ? "0" : "") + formattedSeconds); }
