Date today   new Date    Date tomorrow   new Date today getTime      1000   60   60   24      Date has a constructor using the milliseconds since the UNIX-epoch  the getTime  -method gives you that value  So adding the milliseconds for a day  does the trick  If you want to do such manipulations regularly I recommend to define constants for the values   Important hint  That is not correct in all cases  Read the WARNING comment  below

Given a Date dt you have several possibilities   Solution 1  You can use the Calendar class for that   Date dt   new Date    Calendar c   Calendar getInstance     c setTime dt    c add Calendar DATE  1   dt   c getTime      Solution 2  You should seriously consider using the Joda-Time library  because of the various shortcomings of the Date class  With Joda-Time you can do the following   Date dt   new Date    DateTime dtOrg   new DateTime dt   DateTime dtPlusOne   dtOrg plusDays 1     Solution 3  With Java 8 you can also use the new JSR 310 API  which is inspired by Joda-Time    Date dt   new Date    LocalDateTime from dt toInstant    plusDays 1

In very special case If you asked to do your own date class  possibly from your Computer Programming Professor  This method would do very fine job   public void addOneDay        int    months    31  28  31  30  31  30  31  31  30  31  30  31       day        if  day gt  months month-1            month            day   1          if  month  gt  12               year                month   1

tl dr  LocalDate of  2017   Month JANUARY   23              plusDays  1     java time  Best to avoid the java util Date class altogether  But if you must do so  you can convert between the troublesome old legacy date-time classes and the modern java time classes  Look to new methods added to the old classes   Instant  The Instant class  is close to being equivalent to Date  both being a moment on the timeline  Instant resolves to nanoseconds  while Date is milliseconds   Instant instant   myUtilDate toInstant       You could add a day to this  but keep in mind this in UTC  So you will not be accounting for anomalies such as Daylight Saving Time  Specify the unit of time with the ChronoUnit class   Instant nextDay   instant plus  1   ChronoUnit DAYS       ZonedDateTime  If you want to be savvy with time zones  specify a ZoneId to get a ZonedDateTime  Specify a proper time zone name in the format of continent region  such as America Montreal  Africa Casablanca  or Pacific Auckland  Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones  not standardized  and not even unique       ZoneId z   ZoneId of   America Montreal      ZonedDateTime zdt   instant atZone  z     ZonedDateTime zdtNextDay   zdt plusDays  1       You can also represent your span-of-time to be added  the one day  as a Period   Period p   Period ofDays  1     ZonedDateTime zdt   ZonedDateTime now  z   plus  p       You may want the first moment of that next day  Do not assume the day starts at 00 00 00  Anomalies such as Daylight Saving Time  DST  mean the day may start at another time  such as 01 00 00  Let java time determine the first moment of the day on that date in that zone   LocalDate today   LocalDate now  z     LocalDate tomorrow   today plus  p     ZonedDateTime zdt   tomorrow atStartOfDay  z         About java time  The java time framework is built into Java 8 and later  These classes supplant the troublesome old legacy date-time classes such as java util Date  Calendar   amp  SimpleDateFormat   The Joda-Time project  now in maintenance mode  advises migration to the java time classes   To learn more  see the Oracle Tutorial  And search Stack Overflow for many examples and explanations  Specification is JSR 310   You may exchange java time objects directly with your database  Use a JDBC driver compliant with JDBC 4 2 or later  No need for strings  no need for java sql   classes   Where to obtain the java time classes     Java SE 8  Java SE 9  Java SE 10  and later   Built-in   Part of the standard Java API with a bundled implementation  Java 9 adds some minor features and fixes   Java SE 6 and Java SE 7   Much of the java time functionality is back-ported to Java 6  amp  7 in ThreeTen-Backport   Android   Later versions of Android bundle implementations of the java time classes  For earlier Android   lt 26   the ThreeTenABP project adapts ThreeTen-Backport  mentioned above   See How to use ThreeTenABP        The ThreeTen-Extra project extends java time with additional classes  This project is a proving ground for possible future additions to java time  You may find some useful classes here such as Interval  YearWeek  YearQuarter  and more     Update  The Joda-Time library is now in maintenance mode  The team advises migration to the java time classes  I am leaving this section intact for history   Joda-Time  The Joda-Time 2 3 library makes this kind of date-time work much easier  The java util Date class bundled with Java is notoriously troublesome  and should be avoided   Here is some example code    Your java util Date is converted to a Joda-Time DateTime object  Unlike a j u Date  a DateTime truly knows its assigned time zone  Time zone is crucial as adding a day to get the same wall-clock time tomorrow might mean making adjustments such as for a 23-hour or 25-hour day in the case of Daylight Saving Time  DST  here in the United States  If you specify the time zone  Joda-Time can make that kind of adjustment  After adding a day  we convert the DateTime object back into a java util Date object   java util Date yourDate   new java util Date        Generally better to specify your time zone rather than rely on default  org joda time DateTimeZone timeZone   org joda time DateTimeZone forID   America Los Angeles     DateTime now   new DateTime  yourDate  timeZone    DateTime tomorrow   now plusDays  1    java util Date tomorrowAsJUDate   tomorrow toDate      Dump to console     System out println   yourDate      yourDate    System out println   now      now    System out println   tomorrow      tomorrow    System out println   tomorrowAsJUDate      tomorrowAsJUDate      When run     yourDate  Thu Apr 10 22 57 21 PDT 2014 now  2014-04-10T22 57 21 535-07 00 tomorrow  2014-04-11T22 57 21 535-07 00 tomorrowAsJUDate  Fri Apr 11 22 57 21 PDT 2014

I prefer joda for date and time arithmetics because it is much better readable   Date tomorrow   now   plusDays 1  toDate      Or  endOfDay now   plus days 1    toDate   startOfDay now   plus days 1    toDate

To make it a touch less java specific  the basic principle would be to convert to some linear date format  julian days  modified julian days  seconds since some epoch  etc  add your day  and convert back   The reason for doing this is that you farm out the  get the leap day  leap second  etc right  problem to someone who has  with some luck  not mucked this problem up   I will caution you that getting these conversion routines right can be difficult  There are an amazing number of different ways that people mess up time  the most recent high profile example was MS s Zune   Dont  poke too much fun at MS though  it s easy to mess up   It doesn t help that there are multiple different time formats  say  TAI vs TT

I will show you how we can do it in Java 8  Here you go   public class DemoDate       public static void main String   args            LocalDate today   LocalDate now            System out println  Current date      today              add 1 day to the current date         LocalDate date1Day   today plus 1  ChronoUnit DAYS           System out println  Date After 1 day       date1Day             The output   Current date  2016-08-15 Date After 1 day   2016-08-16

As mentioned in the Top answer  since java 8 it is possible to do   Date dt   new Date    LocalDateTime from dt toInstant    plusDays 1     but this can sometimes lead to an DateTimeException like this    java time DateTimeException  Unable to obtain LocalDateTime from TemporalAccessor  2014-11-29T03 20 10 800Z of type java time Instant   It is possible to avoid this Exception by simply passing the time zone   LocalDateTime from dt toInstant   atZone ZoneId of  UTC     plusDays 1
