String input = "What's the story's story?";
String output = input.replaceAll("'", "\\\\'");

I used the following class to test this:

public class TestReplaceAll {
    public static void main(String[] args) {
        String input = "";
        String regex = "";
        String replacement = "";
        try {
            input = args[0];
            regex = args[1];
            replacement = args[2];
        } catch (ArrayIndexOutOfBoundsException e) {
            System.out.println(
                "usage: java TestReplaceAll input regex replace");
            System.exit(1);
        }

        String output = input.replaceAll(regex, replacement);
        System.out.println(output);
        System.exit(output.equals(input) ? 1 : 0);
    }
}

I'd imagine this has more to do with The Java Language spec's take on
literal string specification than it has to do with the specifics of
String.replaceAll().
