Try as follows...

  SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
  Date date;

 @SuppressLint("SimpleDateFormat") 
 public static Date getDate(String string){

         date = new Date();

         try {
                date = format.parse(string);
        }     catch (ParseException e) {
                e.printStackTrace();
        }

       return date; 
  }

Just to improve this, I would define format as a static final at clas level as yo only ever need to create it once, and it then could be reused in other methods.

In addition with your point...I also like to declare the 'Date' object at class level...but, for only for solution, I gave the above solution. thanks for your point.

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

Date testDate = null;

try {
      testDate = sdf.parse("2013-11-12");
}
catch(Exception ex) {
      ex.printStackTrace();
}

int date= testDate.getDate();
int month = testDate.getMonth();
int year = testDate.getYear();

lowercase m matches minute, not month. The OP needs uppercase M as all the other answers indicate.

np, we found the same bug in a logging utility someone else had written in production code last week! BTW I would also make sdf a class static final as it's reusuable

Just use SimpleDateFormat (click the link to see all format patterns).

String string = "2014-02-22";
Date date = new SimpleDateFormat("yyy-M-d", Locale.ENGLISH).parse(string);
System.out.println(date); // Sat Jan 02 00:00:00 BOT 2010

Here's an extract of relevance from the javadoc, listing all available format patterns:

G   Era designator       Text               AD
y   Year                 Year               1996; 96
M   Month in year        Month              July; Jul; 07
w   Week in year         Number             27
W   Week in month        Number             2
D   Day in year          Number             189
d   Day in month         Number             10
F   Day of week in month Number             2
E   Day in week          Text               Tuesday; Tue
u   Day number of week   Number             1
a   Am/pm marker         Text               PM
H   Hour in day (0-23)   Number             0
k   Hour in day (1-24)   Number             24
K   Hour in am/pm (0-11) Number             0
h   Hour in am/pm (1-12) Number             12
m   Minute in hour       Number             30
s   Second in minute     Number             55
S   Millisecond          Number             978

Yes my string variable is the parameter which is your format, your format in SimpleDateFormat was not matching, hence the issue

Rohit Jain Over a year ago

I'm not the OP. But what do you mean by - Don't do it, that's the hard way.? OP is already using SimpleDateFormat.
