I ma getting exeception while parsing the date.
following is the code:
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-DD");
Date d = format.parse("2014/02/20");
System.out.println(d);

Not only have you got the slashes/dashes wrong, you're also using DD (day of year) instead of dd (day of month). You want:
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
As always, read the documentation to find out exactly what pattern symbols mean - and if you find it's behaving oddly, check the pattern against the data very carefully.
I would also recommend:
- Using Joda Time (pre-Java-8) or
java.time(Java 8) if you possibly can; thejava.util.Date/CalendarAPI is horrible - Specifying the locale explicitly
- Specifying the time zone explicitly
Currently you're using the default time zone and locale. While the locale may not matter in this case (unless it's used to pick the calendar system; I can't remember offhand) I think it's clearer to explicitly specify it. The time zone definitely matters; if you only ever want to treat this as a date (no time) it's probably worth specifying UTC - that way it's easy to interoperate with anything else, and you get day boundaries in obvious places in the underlying millisecond representation.

Just realized the second issue... :D
Your dateformat doesn't match your string.
Date d = format.parse("2014-02-20");
or
SimpleDateFormat format = new SimpleDateFormat("yyyy/MM/dd");

DD is for day in a year (this is not me who downvoted)

@SashaSalauyou Thanks for correction, did not notice that.
java.time
In modern Java, use LocalDate class to represent a date-only value, without time-of-day, and without time zone or offset-from-UTC.
Replace the / separators with - to comply with ISO 8601 standard format.
LocalDate ld = LocalDate.parse( "2014/02/20".replace( "/" , "-" ) ) ;
Or define a formatter.
DateTimeFormatter f = DateTimeFormatter.ofPattern( "uuuu/MM/dd" ) ;
LocalDate ld = LocalDate.parse( "2014/02/20" , f ) ;
