import java.util.Calendar;

public class  TestDate

int i=0;
while(stringTokenizer.hasMoreElements()){
//System.out.println(".......................:"+(String)stringTokenizer.nextElement());
values[i]=(String)stringTokenizer.nextElement();
System.out.println("..................values["+i+"]:"+values[i]);

}
input.set(new Integer(values[2]),new Integer(values[0]),new Integer(values[1]));

So, 31 August 2009 is in the future, so it is correct that it says it is after the current date.

Can you explain more clearly what you don't understand?

[Madhu Sudhana]

todays date is 08/31/2007. then It should not be future,right ?

[Michael Dunn]

assuming 08/31/2009 is a typo, in java terms 31 August is 07/31/2007
months are 0-based

Hi,
I have seen your code. There was an error in the line beginning with "input.set" part of your code. You forget that input is an instance of Calender and its arguments must contain primitive integers and not Integer objects.
First remove your error by writing

  (new Integer(values[2])).intValue()) in that part of code.
  

Secondly, write properly what is your problem regarding current date.

What I understand with your problem is; you want to compare user input date with the current system date.

Tell me whether the user-input date could be less than system date or not.

Note: It might be possible in future that I can't respond soon due to time-shortage. But if I have time, then surely I visit javaranch.
