tl dr   Use modern java time classes   Never use Date Calendar SimpleDateFormat classes    Example   ZonedDateTime                                   Represent a moment as seen in the wall-clock time used by the people of a particular region  a time zone    now                                            Capture the current moment      ZoneId of   Africa Tunis                    Always specify time zone using proper  Continent Region  format  Never use 3-4 letter pseudo-zones such as EST  PDT  IST  etc     truncatedTo                                    Lop off finer part of this value      ChronoUnit MILLIS                           Specify level of truncation via  ChronoUnit  enum object                                                  Returns another separate  ZonedDateTime  object  per immutable objects pattern  rather than alter     mutate     the original   format                                         Generate a  String  object with text representing the value of our  ZonedDateTime  object      DateTimeFormatter ISO LOCAL DATE TIME       This standard ISO 8601 format is close to your desired output                                                  Returns a  String    replace   T                                    Replace  T  in middle with a SPACE    java time  The modern approach uses java time classes that years ago supplanted the terrible old date-time classes such as Calendar  amp  SimpleDateFormat      want current date and time    Capture the current moment in UTC using Instant    Instant instant   Instant now       To view that same moment through the lens of the wall-clock time used by the people of a particular region  a time zone   apply 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   Pacific Auckland      ZonedDateTime zdt   instant atZone  z       Or  as a shortcut  pass a ZoneId to the ZonedDateTime now method   ZonedDateTime zdt   ZonedDateTime now  ZoneId of   Pacific Auckland          The java time classes use a resolution of nanoseconds  That means up to nine digits of a decimal fraction of a second  If you want only three  milliseconds  truncate  Pass your desired limit as a ChronoUnit enum object   ZonedDateTime  now       ZoneId of   Pacific Auckland        truncatedTo      ChronoUnit MILLIS        in    dd MM yyyy HH mm ss SS    format   I recommend always including the offset-from-UTC or time zone when generating a string  to avoid ambiguity and misunderstanding    But if you insist  you can specify a specific format when generating a string to represent your date-time value  A built-in pre-defined formatter nearly meets your desired format  but for a T where you want a SPACE   String output        zdt format  DateTimeFormatter ISO LOCAL DATE TIME        replace   T                   sdf1 applyPattern  dd MM yyyy HH mm ss SS         Date date   sdf1 parse strDate     Never exchange date-time values using text intended for presentation to humans   Instead  use the standard formats defined for this very purpose  found in ISO 8601   The java time use these ISO 8601 formats by default when parsing generating strings   Always include an indicator of the offset-from-UTC or time zone when exchanging a specific moment  So your desired format discussed above is to be avoided for data-exchange  Furthermore  generally best to exchange a moment as UTC  This means an Instant in java time  You can exchange a Instant from a ZonedDateTime  effectively adjusting from a time zone to UTC for the same moment  same point on the timeline  but a different wall-clock time   Instant instant   zdt toInstant     String exchangeThisString   instant toString          2018-01-23T01 23 45 123456789Z   This ISO 8601 format uses a Z on the end to represent UTC  pronounced    Zulu         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  Java SE 11  and later  - 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   Most 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

Disclaimer  this answer does not endorse the use of the Date class  in fact it   s long outdated and poorly designed  so I   d rather discourage it completely   I try to answer a regularly recurring question about date and time objects with a format  For this purpose I am using the Date class as example  Other classes are treated at the end   You don   t want to  You don   t want a Date with a specific format  Good practice in all but the simplest throw-away programs is to keep your user interface apart from your model and your business logic  The value of the Date object belongs in your model  so keep your Date there and never let the user see it directly  When you adhere to this  it will never matter which format the Date has got  Whenever the user should see the date  format it into a String and show the string to the user  Similarly if you need a specific format for persistence or exchange with another system  format the Date into a string for that purpose  If the user needs to enter a date and or time  either accept a string or use a date picker or time picker   Special case  storing into an SQL database  It may appear that your database requires a specific format  Not so  Use yourPreparedStatement setObject yourParamIndex  yourDateOrTimeObject  where yourDateOrTimeObject is a LocalDate   Instant  LocalDateTime or an instance of an appropriate date-time class from java time  And again don   t worry about the format of that object  Search for more details   You cannot  A Date hasn   t got  as in cannot have a format  It   s a point in time  nothing more  nothing less  A container of a value  In your code sdf1 parse converts  your string into a Date object  that is  into a point in time  It doesn   t keep the string nor the format that was in the string   To finish the story  let   s look at the next line from your code too       System out println  Current date in Date Format    date     In order to perform the string concatenation required by the   sign Java needs to convert your Date into a String first  It does this by calling the toString method of your Date object  Date toString always produces a string like Thu Jan 05 21 10 17 IST 2012  There is no way you could change that  except in a subclass of Date  but you don   t want that   Then the generated string is concatenated with the string literal to produce the string printed by System out println   In short    format    applies only to the string representations of dates  not to the dates themselves   Isn   t it strange that a Date hasn   t got a format   I think what I   ve written is quite as we should expect  It   s similar to other types  Think of an int  The same int may be formatted into strings like 53 551  53 551  with a dot as thousands separator   00053551   53 551 or even 0x0000 D12F  All of this formatting produces strings  while the int just stays the same and doesn   t change its format  With a Date object it   s exactly the same  you can format it into many different strings  but the Date itself always stays the same   Can I then have a LocalDate  a ZonedDateTime  a Calendar  a GregorianCalendar  an XMLGregorianCalendar  a java sql Date  Time or Timestamp in the format of my choice   No  you cannot  and for the same reasons as above  None of the mentioned classes  in fact no date or time class I have ever met  can have a format  You can have your desired format only in a String outside your date-time object   Links   Model   view   controller on Wikipedia All about java util Date on Jon Skeet   s coding blog Answers by Basil Bourque and Pitto explaining what to do instead  also using classes that are more modern and far more programmer friendly than Date

If you are using JAVA8 API then this code will help   DateTimeFormatter formatter   DateTimeFormatter ofPattern  yyyy-MM-dd HH mm ss    String dateTimeString   LocalDateTime now   format formatter   System out println dateTimeString     It will print the date in the given format   But if you again create a object of LocalDateTime it will print the  T  in between the date and time   LocalDateTime dateTime   LocalDateTime parse dateTimeString  formatter   System out println dateTime toString       So as mentioned in earlier posts as well  the representation and usage is different   Its better to use  yyyy-MM-dd T HH mm ss  pattern and convert the string date object accordingly

You can t - because you re calling Date toString   which will always include the system time zone if that s in the default date format for the default locale  The Date value itself has no concept of a format  If you want to format it in a particular way  use SimpleDateFormat format      using Date toString   is almost always a bad idea

The output in your first printline is using your formatter  The output in your second  the date created from your parsed string  is output using Date toString which formats according to its own rules  That is  you re not using a formatter   The rules are as per what you re seeing and described here  http   docs oracle com javase 6 docs api java util Date html toString
