Java Regular expression for money

Question

I wan to make regex for money that can validate amount with Commas, assumed decimals, negative sign or parentheses, dollar sign, decimals, numeric only.

I have used the following expression

((\\$?(([0-9]{0,1})?\\.[0-9]{1,2}))|(\\$?([1-9]{1}[0-9]{0,2}([,][0-9]{3})*)(\\.[0-9]{1,2})?))

It works fine for $23,000 etc. but how to handle negative sign or parentheses

Please advice.

It's amazing that i lost so much reputation by asking question :) it's really de-fostering the user's trust on such system... — , Mar 11 '13 at 09:22

Currency amount US & EU (cents optional) Can use US-style 123,456.78 notation and European-style 123.456,78 notation. Optional thousands separators; optional two-digit fraction

Match; JGsoft:
^[+-]?[0-9]{1,3}(?:[0-9]*(?:[.,][0-9]{2})?|(?:,[0-9]{3})*(?:\.[0-9]{2})?|(?:\.[0-9]{3})*(?:,[0-9]{2})?)$

@vikingsteve, why? That only basic stuff in that regex, no advanced regex feature used. – stema Mar 11 '13 at 09:30
