Java replace issues with ' (apostrophe/single quote) and \ (backslash) together

Question

I seem to be having issues. I have a query string that has values that can contain single quotes. This will break the query string. So I was trying to do a replace to change

Remember that stringToEdit.replaceAll(String, String) returns the result string. It doesn't modify stringToEdit because Strings are immutable in Java. To get any change to stick, you should use

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