[Sridhar Ranganthan]

Hi, please find the below program iam getting the exception


Basically iam try to the format the string[] , this string[] should be different date pattern.

import java.util.*;
import java.text.*;
public class StringToDate {
   public static void main(String[] args) 
	  {

              String a[]={"01-05-2008","05/01/2007","02-JAN-2009","Jan/05/2010","2010/04/01" };   
              String requiredFormat="dd/MM/yyyy";  

              for(int i=0;i<a.length;i++)   
             {
     Format formatter;
     formatter = new SimpleDateFormat(requiredFormat);
     System.out.println(formatter.format(new Date(a[i]))); 
            }     
   }
}   

Iam getting the following exception :-

Exception in thread "main" java.lang.IllegalArgumentException

The Exception explains the problem. Check the format of the dates you are supplying to formatter.

Hi sri,

You are using wrong date format other than "05/01/2007".Check it.

From the javadocs for the Date constructor with a String parameter

the only characters permitted within s are these ASCII characters:

abcdefghijklmnopqrstuvwxyz
ABCDEFGHIJKLMNOPQRSTUVWXYZ
0123456789,+-:/

and whitespace characters.

If the number is followed by whitespace, a comma, a hyphen, or end of string, then if an hour has been recognized but not a minute, it is regarded as a minute; otherwise, if a minute has been recognized but not a second, it is regarded as a second; otherwise, it is regarded as a day of the month.

The first item in the Array is interpreted to be hour minute and second and thus an exception is thrown.

What is exactly the problem you are trying to solve?

Your program parses strings into Date objects. It expects the strings to be in the format "dd/MM/yyyy". Then you put in strings with different formats. Obviously if the string doesn't match the format, you get an exception - that's to be expected.

So, what are you looking for, a program that can parse all those different strings in different formats?

You can catch the ParseException and try to parse the string with a different format, until it parses without an exception.
