You are looking for

str = str.replace("\"", "\\\"")

DEMO

I would avoid using replaceAll since it uses regex syntax in description of what to replace and how to replace, which means that \ will have to be escaped in string "\\" but also in regex \\ (needs to be written as "\\\\" string) which means that we would need to use

str = str.replaceAll("\"", "\\\\\"");

or probably little cleaner:

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

With replace we have escaping mechanism added automatically.
