Check if date is in specified format or not

Question

Hi,
I am reading date from spreadsheet. I want to validate this date, it should follow the format 'MM/dd/yyyy HH:mm'.
I tried it using SimpleDateFormat class
SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yyyy HH:mm");
Date timeStamp;
          try {
               timeStamp = formatter.parse(dateStr);
               System.out.println("----timeStamp :: " +timeStamp);
          } catch (ParseException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          }But when I checked it with dateStr = 14/5/2009 (which is invalid for MM/dd/yyyy HH:mm format), still it dint give any error.
I want to display error message whenever it's not valid.
Somehow I am managing this using method as follows, but is there any other efficient way to achieve this?
public static boolean testDate(String str) {
          int ThirtyOneDayMon = 31;
          int ThirtDayMon = 30;
          boolean flag = true;
          StringTokenizer st = new StringTokenizer(str, "/");
          int month = Integer.parseInt(st.nextToken());
          int day = Integer.parseInt(st.nextToken());
          int year = Integer.parseInt(st.nextToken());
          System.out.println("mon :: " + month + "day :: " + day + "yr" + year);
          if ((month > 12) || (month < 1)) {
               return false;
          switch (month) {
               case 1 : case 3 : case 5 : case 7 : case 9 :
                    if (day > ThirtyOneDayMon) {
                         flag = false;
                    break;
               case 2 :
                    if ((year % 4) == 0) {
                         if (day > 29) {
                              flag = false;
                    } else {
                         if (day > 28) {
                              flag = false;
               case 4 : case 6 : case 8 : case 10 : case 12 :
                    if (day > ThirtDayMon) {
                         flag = false;
                    break;
          return flag;
     }

You forgot this:
formatter.setLenient(false);EDIT: Dammit, masijade. ;-)Yeah, I spelled mine wrong though, and corrected after I saw yours, so we're even. ;-)
