Is there a library or any easy way to convert a string and make sure its compatible as a regex to look for and replace in another string. So if the string is "$money" it would get converted to "\$money". I tried using StringEscapeUtil.escape but it doesn't work with characters such as $.

The method replaceAll() replaces all occurrences of a String in another String matched by regex. This is similar to the replace() function, the only difference is, that in replaceAll() the String to be replaced is a regex while in replace() it is a String.
Java String replaceAll() The replaceAll() method replaces each substring that matches the regex of the string with the specified text.
The plus sign + is a greedy quantifier, which means one or more times. For example, expression X+ matches one or more X characters. Therefore, the regular expression \s matches a single whitespace character, while \s+ will match one or more whitespace characters.
You can use Pattern.quote("$money").

Prepend the \\Q in front of the string, and \\E at the end:
"\\Q$money\\E"
This tells the regex engine that the string between \Q and \E must be interpreted verbatim, ignoring any metacharacters that it may contain.
