OK - off topic, but Sun's java forum sucks, and there are an incredible
number of Java guru's on this list, so I thought I'd throw this out here.
(That and I am using this in a custom validation routine :-)) Any help
would be GREATLY appreciated!
Here's the scenario - I've got a series of static constants that represent
Java regular expressions. These RE's are used to validate driver license
formats for the 50 states + DC. The strings look like this:
public static final String AK = "^[0-9]{1,7}$";
public static final String AL = "^[0-9]{7}$";
public static final String AR = "^[0-9]{8,9}$";
public static final String AZ =
"^[0-9ABDY][0-9]{8}$|^[A-Z][0-9]{3,6}$|^[A-Z]{2}[0-9]{3,5}$";
public static final String CA = "^[A-Z][0-9]{4,7}$";
public static final String CO =
"^[A-Z][0-9]{1,6}$|^[A-Z]{2}[0-9]{1,6}$|^[0-9]{9}$";
etc. etc. etc.
On my form I have a drop-down box of states, and a field for the license
number. In my custom validator routine, I pick up the value of the state,
and build a string to represent the constant - i.e.
private static boolean validateDriversLicenseNumber(String
licenseState, String licenseNumber)
{
String licenseConstant = "Constants." + licenseState;
I then want to use "licenseConstant" in a Pattern / Match:
Pattern p = Pattern.compile(licenseConstant,
Pattern.CASE_INSENSITIVE);
Match m = p.matcher(licenseNumber);
return (m.find());
}
Obviously the line "String licenseConstant = "Constants." + licenseState;"
does not give me the value of Constant.<state name>; the question I have is,
is there a method (or something) that will allow me to build such a string,
and return the value (i.e. the regular expression)? Or is there a better
way of doing this?
TIA!
