Part in my jsp page where I am passing date after submit of this form to the servlet:
<div class="form-group">
<tr>
<td>Date</td>
<td><input type=date step=7 name="day" required="required"> </td>
</tr>
</div>
In my servlet I wrote:
Date day=new Date();
String startDateStr = request.getParameter("day");
System.out.println("stsartdate Str"+startDateStr);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
try {
date=sdf.parse(request.getParameter("startDateStr"));
System.out.println("date entered is="+date);
} catch (ParseException e) {
e.printStackTrace();
}
It is prompting me a null pointer exception.

However, the print statement where I am printing the date fetched from the jsp page in the form of string, it is printing:
stsartdate Str2016-03-10
It is throwing null-pointer exception while executing try block. Kindly get me out of this. Thanks in advance.
