String s = new Integer(i).toString();

OR

String s = "" + i;

The source code is as follows... none of the solutions defined by kotan and bobbit31 worked properly as the program returns some error regarding to NullPointerException. Remember I'm using JBuilder 7 as the development tool n can't b changed due to the need of my assignment. So what's the correct solution......??? It's urgent

   <select name="day">
      <option value="none">Day</option>
<%
  String mday;
  for(int i=1; i<=31; i++)
   {
     mday = new Integer(i).toString();
     if(mday.equals(request.getParameter("day"))){
       out.println("<option selected>" + mday + "</option>");
     }else
     out.println("<option value=" + i + ">" + i + "</option>");
   }
%>
   </select>

bobbit31Commented:
make sure request.getParameter("day") is not null!

you can do this as well:

String day = request.getParameter("day");

if(day != null && mday.equals(day)) {
       out.println("<option selected>" + mday + "</option>");
     }else
     out.println("<option value=" + i + ">" + i + "</option>");
   }

which line is the problem?  
maybe this one?
>   if(mday.equals(request.getParameter("day"))){  
If browser didn't send  "day" then  NPE would occur.

No, that would not create a NPE.

Shut down Tomcat to look at work folder.

I've used this to convert int to String and it works for me.

String myString = new String ();
myString = String.valueOf(i);
