I was wondering if Regex in Java has memory variables like they do in perl. If so, how are they used.

If you mean back references, then yes Java has this. You can refer to a capturing group inside a regular expression using the notation
\1for the first group,\2for the second, etc. Note that inside a string literal the backslashes must be escaped.
