Java: Replace all ' in a string with \'

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.

Thanks,

Iwan

You can use apache's commons-text library (instead of commons-lang):

Example code:

org.apache.commons.text.StringEscapeUtils.escapeJava(escapedString);

Dependency:

compile 'org.apache.commons:commons-text:1.8'

OR

<dependency>
   <groupId>org.apache.commons</groupId>
   <artifactId>commons-text</artifactId>
   <version>1.8</version>
</dependency>
