java util date value of string

Question

This is a method in an EJB for adding booking, I'm trying to set a to value of String Arr because Arr is a string which gets the form value in the Servlet and I want to do the same for d to value of String Dept. I'm using java.util.Date, it works for java.sql.Date but not for java.util.Date.

public void addBooking(String Arr,  String Dept, String username, String roomnum){
    BookingTableClass booking = new BookingTableClass();

    Date a= Date.valueOf(Arr);//the problem is in these four lines
    booking.setarrivalDate(a);
    Date d= Date.valueOf(Dept);
    booking.setdeptDate(d);

            booking.setCustomerUsername(username);  
    Long rmnum = Long.valueOf(roomnum);
    booking.setRoomNumber(rmnum);}

You've shown us where the problem is, but not what the problem is. Can you explain? — mthmulders

Maybe you're not using a correct format for the Date type and you have to specify the format that you're using, for this purpose use SimpleDateFormat class.

SimpleDateFormat textFormat = new SimpleDateFormat("yyyy-MM-dd");
String paramDateAsString = "2007-12-25";
Date myDate = null;

myDate = textFormat.parse(paramDateAsString);

Hope it helps. Best regards.

You can convert a java.util.Date into a java.sql.Date object like this:

java.util.Date now = new java.util.Date();
java.sql.Date date = new java.sql.Date(now.getTime());

That is, you obtain the java.util.Date equivalent in milliseconds and then use this value to initialize the java.sql.Date object.

SimpleDateFormat formatter = new SimpleDateFormat("dd/mm/yyyy"); Date a=null; try { a = formatter.parse(Arr); } catch (ParseException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } booking.setarrivalDate(a); Date d=null; try { d = formatter.parse(Dept); } catch (ParseException e1) { // TODO Auto-generated catch block e1.printStackTrace(); }
