Convert time field H:M into integer field (minutes) in JAVA

Question

The JTable includes the time field, e.g. \"01:50\". I need to read this value into the integer variable. For this I´d like to convert time into minutes. For instance \"01:50

Answer 1

I don't think using Calendar/Date will be better than straightforward parse for this case. If your time format is indeed H:m, then I don't think you need anything more complex than this:

/**
 * @param s H:m timestamp, i.e. [Hour in day (0-23)]:[Minute in hour (0-59)]
 * @return total minutes after 00:00
 */
private static int toMins(String s) {
    String[] hourMin = s.split(":");
    int hour = Integer.parseInt(hourMin[0]);
    int mins = Integer.parseInt(hourMin[1]);
    int hoursInMins = hour * 60;
    return hoursInMins + mins;
}
