Hi Folks,
I have been searching to find a reglular expression that deals with decimal points, they are not mentioned on the Sun Tutorials for Regular Expressions. Basically im trying to verify that a string taken in from a screen matches the format of (15).99. This is not for my homework assignment:-) If anyone even knows of a good tutorial that covers this, that would be great as im kinda new to Java development.

Thanks

1. check for the number of decimal points in the input. if this is not 1 => false
2. check that everything before the decimal point is a decimal. if not => false
3. check that everything after the decimal point is a decimal if not so=> false
4. check the number of decimals after the decimal pont. if not two => false

if all these checks cleared, you've got a match. don't know whether or not regex has a quick sollution for it, but you could as well do it without

Cool Thanks very much, i actually worked it out, i had been using "[0-9]{0,15}.{1}[0-9]{2}" and i have since found that this "[0-9]{0,15}[.]{1}[0-9]{2}" will work.

Thanks

You can simplify it just a little more with a digit character match like so You might find this small regex testing form that I posted a while back helpful in tweaking patterns as you are experimenting: http://www.daniweb.com/forums/post392585-8.html
The numbered text fields at the bottom are the match group results of the pattern.

Thanks very much for all your help.
