You may need to format
the out put as follows.
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Date convertedCurrentDate = sdf.parse("2013-09-18");
String date=sdf.format(convertedCurrentDate );
System.out.println(date);
Use
String convertedCurrentDate =sdf.format(sdf.parse("2013-09-18"));
Output:
2013-09-18
