How to get the hours with minutes between two LocalTime times

Question

Right now, I can get the hours between two LocalTime times like this:

public long getHours(){
        return ChronoUnit.HOURS.between(this.timeIn, this.timeOut);
    }

But the result is only the number of hours. What I want is to also include the minutes as well. So for example if 5 hours and 30 minutes passed the result to be 5.30.

EDIT: For example timeIn is 10:00:00 and time out is 15:30:00. I want the hours and minutes between these two times

sure timeIn it's just LocalTime.now and timeOut is LocalTime.of so we can say that time in is 10:00:00 and time out is 15:30:00 — AStudentWithQuestionsandAnswer, Dec 27 '22 at 13:33
public long getHours(){ return ChronoUnit.MINUTES.between(this.timeIn, this.timeOut) / 60; } won't do the trick? — Tom Carmi, Dec 27 '22 at 13:38

You can use the Duration.between method from the java.time API:

public static Duration getDuration(){
    LocalTime timeIn  = LocalTime.now();;
    LocalTime timeOut = timeIn.plusHours(5).plusMinutes(30).plusSeconds(23);
    return Duration.between(timeIn, timeOut);
}

Returned for above example:

PT5H30M23S

That text is in standard ISO 8601 format.

To format it differently use the methods toXXXPart() from the Duration class:

public static String format(Duration duration) {
    return String.format("%02d:%02d:%02d", duration.toHoursPart(), duration.toMinutesPart(), duration.toSecondsPart());
}

A sample output with the same above example:

System.out.println(format(getDuration()));

prints

05:30:23
