I need to escape all quotes (') in a string, so it becomes \' I've tried using replaceAll, but it doesn't do anything. For some reason I can't get the regex to work. I'm trying with String s = "You'll be totally awesome, I'm really terrible"; String shouldBecome = "You\'ll be totally awesome, I\'m really terrible"; s = s.replaceAll("'","\\'"); // Doesn't do anything s = s.replaceAll("\'","\\'"); // Doesn't do anything s = s.replaceAll("\\'","\\'"); // Doesn't do anything I'm really stuck here, hope somebody can help me here.

I can replace dollar signs by using Matcher.quoteReplacement. I can replace words by adding boundary characters: from = "\\b" + from + "\\b"; outString = line.replaceAll(from, to); But I can't seem to combine them to replace words with dollar signs. Here's an example. I am trying to replace " $temp4 " (NOT $temp40 ) with " register1 ". String line = "add, $temp4, $temp40, 42"; String to = "register1"; String from = "$temp4"; String outString; from = Matcher.quoteReplacement(from); from = "\\b" + from + "\\b"; //do whole word replacement outString = line.replaceAll(from, to); System.out.println

Pretty simple question, but this is coming from a C/C++ person getting into the intricacies of Java. I understand I can fire up jUnit and a few performance tests of my own to get an answer; but I'm just wondering if this is out there. Are there known difference(s) between String.replaceAll() and Matcher.replaceAll() (On a Matcher Object created from a Regex.Pattern) in terms of performance? Also, what are the high-level API 'ish differences between the both? (Immutability, Handling NULLs, Handling empty strings, making coffee etc.) According to the documentation for String.replaceAll , it has
