If this part "&#92;&#92;d*?&#92;&#92;.?&#92;&#92;d*" means "zero or more reluctantly from [0-9], followed by an optional full stop, followed by zero or more greedily from [0-9]", then it's the same. I remember regular expressions being surrounded by forward slashes in Javascript, but I don't know what the gee after the expression means. I will check that out and get back to you.

Edit: I understand that the gee flag at the end means that it's a global search. I believe that in Java, that's unnecessary and instead this is done through methods of the Pattern class or the matcher class. Check out the API for those two classes.

I didn't think javascript actually supported &#92;d or &#92;s or any of that nice fancy stuff, it's real bare-metal basics according to the spec. how about a tutorial?

I googled java regex and found 2 nice links.
