Add two String Times in java [duplicate]

Answer 1

Keep in mind that you can convert int values for hours/minutes/seconds to a single int like this:

int totalSeconds = ((hours * 60) + minutes) * 60 + seconds;

And convert back:

int hours = totalSeconds / 3600;  // Be sure to use integer arithmetic
int minutes = ((totalSeconds) / 60) % 60;
int seconds = totalSeconds % 60;

Or you can do arithmetic piecemeal as follows:

int totalHours = hours1 + hours2;
int totalMinutes = minutes1 + minutes2;
int totalSeconds = seconds1 + seconds2;
if (totalSeconds >= 60) {
  totalMinutes ++;
  totalSeconds = totalSeconds % 60;
}
if (totalMinutes >= 60) {
  totalHours ++;
  totalMinutes = totalMinutes % 60;
}
