    Please clarify your problem space and show pertinent code, both to help us understand you question. – Hovercraft Full Of Eels May 27 '17 at 05:17
  • I know the desired format in that other question is not the same, but the way to do is the same, so I trust you to tailor the answers from the other question to the format you are asking for. – Ole V.V. May 27 '17 at 07:16

Assuming you are using Java 8+, use a DateTimeFormatter

String text = LocalDate.now().format(DateTimeFormatter.ofPattern("yy-MM-dd"));

In earlier versions, use a SimpleDateFormat like

String text = new SimpleDateFormat("yy-MM-dd").format(new Date());

While you can use the later in more recent versions, the former is generally preferred because date and time handling has been greatly improved by the java.time classes.

You can do it by the below code.

public void getCurrentTimeStampInYYMMDDFormat() {
    String date = new SimpleDateFormat("yy-MM-dd").format(new Date());
}

If you are using JDK8 then, you can also do it like this:

public void getCurrentTimeStampInYYMMDDFormat() {
    String date = LocalDateTime.now()
       .format(DateTimeFormatter.ofPattern("yy-MM-dd"));
}

    Obviously ... he needs to modify the pattern if he wants to display the date as YY-MM-DD. The details are **in the javadocs**. – Stephen C May 27 '17 at 05:21

    But the return type I need is Date. – blueblueblue May 27 '17 at 05:40

    @blueblueblue Edit your Question to make clear your requirements. – Basil Bourque May 27 '17 at 06:49

    Ah, one more of those. @blueblueblue, a `Date` cannot have a specific format in it, it’s just a point in time. How you format it lies outside the `Date` object. – Ole V.V. May 27 '17 at 07:06
  • See for example the discussions under [this question: How to initialize Gregorian calendar with date as YYYY-MM-DD format?](https://stackoverflow.com/questions/44180575/how-to-initialize-gregorian-calendar-with-date-as-yyyy-mm-dd-format) That is about `GregorianCalendar`, but no matter if we are talking `Date` or `GregorianCalendar` or `int`, the truth is the same: the variable does not (cannot) hold a string presentation in it. – Ole V.V.
