It also allowed the formatting and parsing of date strings. It allowed the interpretation of dates as year, month, day, hour, minute, and second values. Prior to JDK 1.1, the class Date had two additional functions. It should be simpler! Duration.between(startLocalDateTime, endLocalDateTime).toMillis() The class Date represents a specific instant in time, with millisecond precision. Repeat that for each time unit in descending order.įinally a disclaimer: I didn't take different timezones into account (both dates should be in the same timezone) and I also didn't test/check how daylight saving time or other changes in a calendar (like the timezone changes in Samoa) affect this calculation. Then adjust that date by the number of years so that the start date is less then a year from the end.
The basic idea is this: create a temporary start date and get the full years to the end.
We would like to know how to add one day to LocalDate and minus hours and minutes from LocalDateTime.
prints: 29 years 8 months 24 days 22 hours 54 minutes 50 seconds. Java Data Type How to - Add one day to LocalDate and minus hours and minutes from LocalDateTime. Long seconds = tempDateTime.until( toDateTime, ChronoUnit.SECONDS ) Long minutes = tempDateTime.until( toDateTime, ChronoUnit.MINUTES ) There are two implementations of TemporalAmount provided in JSE: Duration and Period. Long hours = tempDateTime.until( toDateTime, ChronoUnit.HOURS ) public LocalDate minus(TemporalAmount amountToSubtract) This method returns a new instance of LocalDate subtracted by provided TemporalAmount. Long days = tempDateTime.until( toDateTime, ChronoUnit.DAYS ) Long months = tempDateTime.until( toDateTime, ChronoUnit.MONTHS ) Long years = tempDateTime.until( toDateTime, ChronoUnit.YEARS ) LocalDateTime tempDateTime = om( fromDateTime ) LocalDateTime toDateTime = LocalDateTime.of(2014, 9, 10, 6, 40, 45) Here's a way to calculate the difference although not necessarily the fastest: LocalDateTime fromDateTime = LocalDateTime.of(1984, 12, 16, 7, 45, 55) Unfortunately, there doesn't seem to be a period class that spans time as well, so you might have to do the calculations on your own.įortunately, the date and time classes have a lot of utility methods that simplify that to some degree. The example is shown with Date, Calendar, New Java 8 and Apache commons API.Īccumulo,1,ActiveMQ,2,Adsense,1,API,37,ArrayList,18,Arrays,24,Bean Creation,3,Bean Scopes,1,BiConsumer,1,Blogger Tips,1,Books,1,C Programming,1,Collection,8,Collections,37,Collector,1,Command Line,1,Comparator,1,Compile Errors,1,Configurations,7,Constants,1,Control Statements,8,Conversions,6,Core Java,149,Corona India,1,Create,2,CSS,1,Date,3,Date Time API,38,Dictionary,1,Difference,2,Download,1,Eclipse,3,Efficiently,1,Error,1,Errors,1,Exceptions,8,Fast,1,Files,17,Float,1,Font,1,Form,1,Freshers,1,Function,3,Functional Interface,2,Garbage Collector,1,Generics,4,Git,9,Grant,1,Grep,1,HashMap,2,HomeBrew,2,HTML,2,HttpClient,2,Immutable,1,Installation,1,Interview Questions,6,Iterate,2,Jackson API,3,Java,32,Java 10,1,Java 11,6,Java 12,5,Java 13,2,Java 14,2,Java 8,128,Java 8 Difference,2,Java 8 Stream Conversions,4,java 8 Stream Examples,12,Java 9,1,Java Conversions,14,Java Design Patterns,1,Java Files,1,Java Program,3,Java Programs,114,Java Spark,1,java.lang,4, found the best way to do this is with ChronoUnit. In this article, We've seen various ways to add minutes to the date or current date-time. Java 8 added with 10 mins : Wed Apr 08 22:20:

Each unit provides an implementation for a method named between to calculate the amount of time between two temporal objects in terms of that specific unit. seconds or days, using TemporalUnit interface. ("After adding 10 mins : " + afterAdding10Mins) ĭate targetTime = Calendar.getInstance().getTime() The Time API in Java 8 represents a unit of date-time, e.g. Long timeInSecs = date.getTimeInMillis() ĭate afterAdding10Mins = new Date(timeInSecs + (10 * 60 * 1000)) ("Current Date and TIme : " + date.getTime())
Adding 10 mins using Date constructor.
