SimpleDateFormat formatter = new SimpleDateFormat("yyyy/MM/dd");
Date date = formatter.parse("2020/05/06");

I need to extract day, month and year from it i.e.

int day = 06;
int  month = 05;
int year = 2020;

but when I use

int day = date.getDay();
int month = date.getMonth();
int day = date.getYear();

its not working.

    _its not working._ What does that mean? Please provide a [mcve], and see [ask], [help/on-topic]. – AMC Jun 29 '20 at 17:51
  • Probably expecting the day of the month? IIRC in Java and JS it's `getDate`. – José Pedro Jun 29 '20 at 19:58

    I recommend you don’t use `SimpleDateFormat` and `Date`. Those classes are poorly designed and long outdated, the former in particular notoriously troublesome. Instead use `LocalDate` and `DateTimeFormatter`, both from [java.time, the modern Java date and time API](https://docs.oracle.com/javase/tutorial/datetime/). – Ole V.V. Jun 30 '20 at 05:38

  • Even if you insisted on using `Date`, you should still stay far away from the deprecated `getXxxx`methods. They have been deprecated since February 1997 because they work unreliably across time zones. – Ole V.V. Jun 30 '20 at 05:41

Don't use Date as it is deprecated. Use LocalDate and DateTimeFormatter as follows.

LocalDate ld  = LocalDate.parse("2020/05/06", 
              DateTimeFormatter.ofPattern("yyyy/MM/dd"));
int year = ld.getYear();
int month = ld.getMonthValue();
int day = ld.getDayOfMonth();
System.out.println(month + " " + day + " " + year);

Prints

5 6 2020

Check out the other date/time related classes in the java.time package.

It's much better to use the new api as answered by WJS but if for some reason you want to use the old api you should use Calendar

SimpleDateFormat formatter = new SimpleDateFormat("yyyy/MM/dd");
formatter.parse("2020/11/06");
Calendar calendar = formatter.getCalendar();

int day = calendar.get(Calendar.DAY_OF_MONTH);
int month = calendar.get(Calendar.MONTH) + 1; // add 1 because it returns 0-11
int year = calendar.get(Calendar.YEAR);

System.out.println(day);
System.out.println(month);
System.out.println(year);
