Method

StringgetHoursFromMillis(long ms)
get Hours From Millis 
double numSeconds = ((ms) / 1000d);
return String.valueOf(numSeconds / 3600);
longgetHoursIntoMilliseconds(int nbHours)
get Hours Into Milliseconds 
return ((long) nbHours) * 3600 * 1000;
intgetHourSpareFromMilliSecond(int milliSecond)
get Hour Spare From Milli Second 
return (milliSecond) % (60 * 60 * 1000);
longgetMilliSecondByHourAndMins(int hour, int min)
get Milli Second By Hour And Mins 
return hour * 60 * 60 * 1000 + min * 60 * 1000;
longgetMillisFromHours(String hours)
Edited this method by adding a nested try catch block that will parse input when the use enters the time in ##h##m format, it will also handle any format in ##H##M, ##h, ##H, ##m, ##M.

longmilliseconds(long p_days, long p_hours, long p_minutes, long p_hoursPerBusinessDay)
Convert the given number of days, hours, and minutes into the corresponding number of milliseconds. 
long seconds = p_days * p_hoursPerBusinessDay * MINUTES_PER_HOUR * SECONDS_PER_MINUTE;
seconds += p_hours * MINUTES_PER_HOUR * SECONDS_PER_MINUTE;
seconds += p_minutes * SECONDS_PER_MINUTE;
return seconds * MILLIS_PER_SECOND;
StringmillisecondsToHours(long ms)
Convert from milliseconds to hours. 
int hours = (int) (ms / (MS_PER_S * S_PER_M * M_PER_H));
return hours + "h";
DoublemillisecondToHour(Long millisecond)
millisecond To Hour 
return (millisecond) / (3600 * 1000 * 1d);
doublemillisToHours(double millis)
_more_ 
return millis / 1000 / 60 / 60;
