Java regex matching with or clause

Question

I've got the following code

String valuepairName = "sc_mpl_MAX_AUD_TIME_To_20_Val.$$DATE_TO_LOAD";
boolean result = valuepairName.matches("sc_mpl_MAX_AUD_TIME_To_(20|32|82)_Val.$$DATE_TO_LOAD");

The result evaluates to false, but I cannot see the mistake. This must be very trivial, hence it's driving me crazy :(

You need to escape each $ individually (or use pattern.quote) ($ is a special character in regex). Use

boolean result = valuepairName.matches("sc_mpl_MAX_AUD_TIME_To_(20|32|82)_Val.\\$\\$DATE_TO_LOAD");

This worked. Didn't think of escaping those dollar signs. Many thanks! :) – 4Kings Sep 07 '16 at 07:38
@4Kings - As mentioned by LukStorms, you might want to escape the `.` as well – TheLostMind Sep 07 '16 at 07:41
