So Trivial: Write "" in Java

This is the most trivial question but I cannot figure out how to solve this.

In a String I want to relace all the occurences of this string " with this ""

My problem is that the compiler wont allow me to write """" or '""' (hope this makes sense).

So my code is:

s = s.replace('"', '""'); // so the 2nd parameter of the method is causing an error

I hope this makes sense :P

EDIT: (using replace instead of replaceAll per suggestion)

s = s.replace("\"", "\"\"");

StackOverflowException's answer is correct. you need to escape quotes with a blackslash

keep in mind that (unlike some other languages) single quotes are for single characters and double quotes are for strings of 0 or more characters

e.g.

'a'   'b'   '1'   '\"' 
""   "a"   "this is a string"
