Java Utililty Methods TimeUnit Usage

String age(long creationDate)
age

String calculateRuntime(long startTime, long endTime)
calculate Runtime

long runTime = endTime - startTime;

String calculateTime(final int seconds)
calculate Time

final int day = (int) TimeUnit.SECONDS.toDays(seconds);
final long hours = TimeUnit.SECONDS.toHours(seconds) - TimeUnit.DAYS.toHours(day);
final long minute = TimeUnit.SECONDS.toMinutes(seconds) - TimeUnit.DAYS.toMinutes(day)

 minute, second);
...

String calculateTime(float seconds)
Returns a string representation of elapsed time from seconds to days:hr:min:s

double partialSeconds = (double) (seconds - ((int) seconds));
int milliseconds = (int) (partialSeconds * 1000);
long secs = (long) seconds;
int day = (int) TimeUnit.SECONDS.toDays(secs);
long hours = TimeUnit.SECONDS.toHours(secs) - (day * 24);
long minute = TimeUnit.SECONDS.toMinutes(secs) - (TimeUnit.SECONDS.toHours(secs) * 60);
long second = TimeUnit.SECONDS.toSeconds(secs) - (TimeUnit.SECONDS.toMinutes(secs) * 60);

Future cancelledFuture()
Returns a cancelled Future .

return CANCELLED_FUTURE;

String convertMilisecondsToDetail(long ms)
convert Miliseconds To Detail

String detail = String.format("%d days, %d hours, %d min and %d sec(s)", TimeUnit.MILLISECONDS.toDays(ms),
