I have Java string:
String b = "/feedback/com.school.edu.domain.feedback.Review$0/feedbackId"); I also have generated pattern against which I want to match this string:
String pattern = "/feedback/com.school.edu.domain.feedback.Review$0(.)*"; When I say b.matches(pattern) it returns false. Now I know dollar sign is part of Java RegEx, but I don't know how should my pattern look like. I am assuming that $ in pattern needs to be replaced by some escape characters, but don't know how many. This $ sign is important to me as it helps me distinguish elements in list (numbers after dollar), and I can't go without it.

$ means "Match the end of the string" (the position after the last character in the string).
You can escape dollar signs with a backslash or with another dollar sign. So $, $$, and \$ all replace with a single dollar sign.
"Java does allow the dollar sign symbol $ to appear in an identifier, but these identifiers have a special meaning, so you should not use the $ symbol in your identifiers."
$0 = the entire matched substring (corresponding to matcher. group()), $1 = the first parenthesized match subpattern (corresponding to matcher.
Use
String escapedString = java.util.regex.Pattern.quote(myString) to automatically escape all special regex characters in a given string.
