There are numerous answers given but I am unable to find compatible with my situation. I need to find difference of 8 hours in time as well as on date change too. Like if time is greater then 8 hours then do not execute something .
Do we have any method which achieve the same in LocalDateTime in Java-8?
I have tried to use following but unable to achieve the same.
LocalDateTime fromDateTime = LocalDateTime.of(2017, 07, 07, 07, 00, 55);
LocalDateTime toDateTime = LocalDateTime.now();
LocalDateTime tempDateTime = LocalDateTime.from(fromDateTime);
long years = tempDateTime.until(toDateTime, ChronoUnit.YEARS);
tempDateTime = tempDateTime.plusYears(years);
long months = tempDateTime.until(toDateTime, ChronoUnit.MONTHS);
tempDateTime = tempDateTime.plusMonths(months);
long days = tempDateTime.until(toDateTime, ChronoUnit.DAYS);
tempDateTime = tempDateTime.plusDays(days);
long hours = tempDateTime.until(toDateTime, ChronoUnit.HOURS);
tempDateTime = tempDateTime.plusHours(hours);
long minutes = tempDateTime.until(toDateTime, ChronoUnit.MINUTES);
tempDateTime = tempDateTime.plusMinutes(minutes);
long seconds = tempDateTime.until(toDateTime, ChronoUnit.SECONDS);
System.out.println("" + java.time.Duration.between(tempDateTime, toDateTime).toHours());
System.out.println(years + " years "
+ months + " months "
+ days + " days "
+ hours + " hours "
+ minutes + " minutes "
+ seconds + " seconds.");
It is difficult to check on time and date separately.
Initially I coded it like but it does not looks correct:
return openBrat!=null
&& openBrat.until(LocalDateTime.now(), ChronoUnit.DAYS) == 0 &&
openBrat.until(LocalDateTime.now(), ChronoUnit.HOURS) >= 8
&& openBrat.until(LocalDateTime.now(), ChronoUnit.Minutes) >= 0;
Could anyone please suggest how to subtract like:
2017 07 06 23:30:00 - 2017 07 07 01:30:00 - Should return 2 hours.
