Get integer value of the current year in Java

Question

I need to determine the current year in Java as an integer  I could just use java util Date    but it is deprecated

If your application is making heavy use of Date and Calendar objects  you really should use Joda Time  because java util Date is mutable  java util Calendar has performance problems when its fields get updated  and is clunky for datetime arithmetic

As some people answered above   If you want to use the variable later  better use   int year   year   Calendar getInstance   get Calendar YEAR     If you need the year for just a condition you better use   Calendar getInstance   get Calendar YEAR    For example using it in a do while that checks introduced year is not less than the current year-200 or more than the current year  Could be birth year    import java util Calendar  import java util Scanner   public static void main  String   args        Scanner scannernumber   new Scanner System in       int year         Checks that the year is not higher than the current year  and not less than the current year - 200 years         do          System out print  Year  Between     Calendar getInstance   get Calendar YEAR  -200    and   Calendar getInstance   get Calendar YEAR                   year   scannernumber nextInt         while year  lt    Calendar getInstance   get Calendar YEAR  -200     year  gt  Calendar getInstance   get Calendar YEAR

tl dr ZonedDateTime now   ZoneId of   quot Africa Casablanca quot                     getYear    Time Zone The answer by Raffi Khatchadourian wisely shows how to use the new java time package in Java 8  But that answer fails to address the critical issue of time zone in determining a date   int year   LocalDate now   getYear     That code depends on the JVM s current default time zone  The default zone is used in determining what today   s date is  Remember  for example  that in the moment after midnight in Paris the date in Montr  al is still  yesterday   So your results may vary by what machine it runs on  a user admin changing the host OS time zone  or any Java code at any moment changing the JVM s current default  Better to specify the time zone  By the way  always use proper time zone names as defined by the IANA  Never use the 3-4 letter codes that are neither standardized nor unique  java time Example in java time of Java 8  int year   ZonedDateTime now   ZoneId of   quot Africa Casablanca quot       getYear      Joda-Time Some idea as above  but using the Joda-Time 2 7 library  int year   DateTime now  DateTimeZone forID   quot Africa Casablanca quot      getYear      Incrementing Decrementing Year If your goal is to jump a year at a time  no need to extract the year number  Both Joda-Time and java time have methods for adding subtracting a year at a time  And those methods are smart  handling Daylight Saving Time and other anomalies  Example in java time  ZonedDateTime zdt        ZonedDateTime      now   ZoneId of   quot Africa Casablanca quot            minusYears  1       Example in Joda-Time 2 7  DateTime oneYearAgo   DateTime now  DateTimeZone forID   quot Africa Casablanca quot      minusYears  1

In Java version 8  can  advised to  use java time library  ISO 8601 sets standard way to write dates  YYYY-MM-DD and java time Instant uses it  so  for UTC    import java time Instant  int myYear   Integer parseInt Instant now   toString   substring 0 4      P S  just in case  and shorted for getting String  not int   using Calendar looks better and can be made zone-aware

You can do the whole thing using Integer math without needing to instantiate a calendar   return  System currentTimeMillis   1000 3600 24 365 25  1970     May be off for an hour or two at new year but I don t get the impression that is an issue
