Thread: Calculate the time in the middle of two hours

hi thanks for your help
How to calculate if today is 22:40:30 and tomorrow is 05:10:45, what hour and minute and second between these two times? That is, exactly what time it is?

Its all arithmetic. There are 24 hours in a day, 60 minutes in an hour and 60 seconds in a minute.
Work in seconds. Get difference, divide by 2, add to first date and convert to H:M:S for results.

It means

 
prayerTimes.get(0) = 05:10:45
prayerTimes.get(4) = 22:40:30
 
String t3 = prayerTimes.get(0);
        String t4 = prayerTimes.get(4);
 
        System.out.println(t3 + "--" + t4);
        System.out.println(Duration.between(
                LocalTime.parse(t4),
                LocalTime.parse(t3)
        ).plusNanos(1).withNanos(0));

after that i don't now how i must find time

Work on the logical steps required to solve the problem BEFORE writing any code.
Can you make a list of the steps required?
