Android: replaceAll() and double quote issue issue

Question

I dont know where I m going wrong.. I want to replace " with "" I have used the following code.

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

this doesnt seem to work. Any suggestions?

Answer 1

Strings are immutable, so you need to assign it into another String:

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

Answer 2

Strings are immutable, so when you "change" your string, you need to reassign it.

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