variables in regex's

Hi, I was wondering how to incorporate a string variable into a
regex. So I've got an array of rules "S -> NP VP" "NP -> dog" etc.,
and a sentence "the dog is blue". I want to match each word in the
sentence to the corresponding rule in my array.
Say the rule "NP -> dog" is myArray[1]. I want something like:
Pattern pattern = Pattern.compile("\bmyArray[1]\b")

I'd appreciate any advice.

Thanks.

Pattern pattern = Pattern.compile("\\b" + myArray[1] + "\\b");
