I suggest you try JavaMonks (or whatever the PerlMonks equivalent is for Java) or stack overflow. PerlMonks would help you convert Java to Perl but going the other way is rather off topic here. Perl is the programming world's equivalent of English	[reply]

The piece of code `qr/$regex/` depends on Perl's implementation of regular expressions and is therefore not directly translatable to Java. It may be translatable if `$regex` only contains a subset of Perl's regex features, but your post does not specify that.	[reply] [d/l] [select]
