regrex

[CaptainPlanet]

I'm trying to use regrex to separate int values from a string. Here is what I have.


Scanner input = new Scanner(System.in);
String date = input.next();

Pattern p = Pattern.compile("-?\\d+");
Matcher ma = p.matcher(date);
ma.find();

while (ma.find())
{
System.out.println(ma.group());
}

It works ok...

I want to take the digits from a date format 02/03/04 or 3/5/2008

My output is
03
04

and
5
2008

Could someone tell me why the first set is being skipped?

Thanks!

ma.find();

while (ma.find()) 
{
    System.out.println(ma.group());
}

Notice you are calling ma.find() twice before you ever call System.out.println();

And the term is regex or RegEx or Regular Expressions. Not regrex.

I kind of pictured in my mind's eye Scooby Doo doing a bit of Java programming.
