simple String question

[Nikos Stavros]

Hi, there

say I wanted to change a String "I'm" in to "I\'m"

would I use this

.replaceAll("'", "\\'");

that doesn't seem to work.

This one will do the trick

 
        String string = "I'm Nice Guy";
        StringBuffer stringbuffer = new StringBuffer(string);
        stringbuffer.insert(stringbuffer.indexOf("'"),"\\");
        System.out.println (stringbuffer);

Well, the behavior is mentioned in the Javadoc.
Apparently, the backslash and the $-sign have a special meaning and you have to do it like:

str = str.replaceAll("'", Matcher.quoteReplacement("\\'"));
