Date Formate Problem

[akhter wahab]

hello i wrote a program that accept date formate like DD/MM/YYYY in a String i have to seprate the DD ,MM,YYYY from this i was doing this by using substring method now problem is when someone give him date like D/MM/YYY or DD/M/YYYY it fails please suggest me how i can seprate these things correctly

Look at the class java.text.DateFormat.

[Rob Spoor]

Parse the String into a Date (java.text.DateFormat)
Convert the Date into a Calendar (java.util.Calendar)
Get the data from the Calendar.

     public static void main(String[] args) {
        DateFormat dateInstance = SimpleDateFormat.getDateInstance();
        System.out.println(dateInstance.format(new Date("1/09/2010")));
    }   

i tried this but not reached on solution

If you read my post (again?) you should be able to do it. You already found a very good DateFormat subclass (SimpleDateFormat). Find the right pattern to create an instance. Use the parse method (I have given you that word for free before).

Using the other class from my post you should now be able to finish this.

      public static void main(String[] args) throws ParseException {
        String value = "1/12/2010";
        DateFormat f = new SimpleDateFormat("mm/dd/yyyy");
        Date date = f.parse(value);
        Calendar c = Calendar.getInstance();
        c.setTime(date);
        System.out.println(c.getTime());
    }  

but its giving me wrong output of date

First take a look at javadoc of SimpleDateFormat

It gives you an example to do what you need. Also I'll give you a clue... mm/dd/yyyy ... 'mm' no way!

i solve my problem using regex but not reached at any solution using java

Was there some particular reason you chose the format "mm/dd/yyyy" to parse a date formatted like "dd/mm/yyyy"?

i am not good is Java enough even these hints not make me able to solve this problem using java thats why i use regex

[Wouter Oet]

You don't need to be good at Java to read the documentation and various hints and concrete code we have given you. This way you're writing code that produces the wanted results but in a manner that is unwanted.

Then you need to re-read the SimpleDateFormat Javadoc page. Hint: the characters in the pattern are case sensitive, and mm does not mean month.
