How to sanitize a String for regexp

Question

I have a java.lang.String that may contain any character possible, is there a easy way to sanitize the string (for example with an additional class that can do that?) and remove all "dangerous" characters for a later java.util.regex.Matcher or regex processing (e.g. $, ^, ...)?

Answer 1

You can use

Pattern.quote(string);

to escape your string for Regex.
