Post some code and we will help you.
But the full code will not be given on a silver platter...

The pseudo code will be something like:

Get the user input.
use a tokenizer to split the string into 3 parts.
get todays date.
todaysdate - userdate.
output what you calculate

@lintwurm

Could you give a quick explanation of what a tokenizer is?

Also, what would you do if you entered a date that was different than the current time?

[lintwurm]

You don't even need to use a tokenizer... You can just use the .split() method to split the string into 3 parts.
for instance:
String[] bla = userInput.split("/");
As far as I remember

bla[0] will now be the dd part
bla[1] will be the mm part
and bla[2] will be the yyyy part.
You can use the systems date method to get the current age.
you can try this:
Date date = new Date();
// Keep the MM upper case
DateFormat df = new SimpleDateFormat("dd-MM-yyyy");
String formattedDate = df.format(date);

That should give you the date in the format you want...
And that is if I remember correctly.

Hope that helps
