Question

final String message =
                        "Please enter the following code in the password reset screen:\n" +
                                "\n"+
                                "{CODE} (((((" + codeStr + ")))))\n" +
                                "If you didn't ask for this code, or don't know what this e-mail is about, you can safely ignore it."
                                .replace("{CODE}", codeStr);

This results in

Please enter the following code in the password reset screen: {CODE} (((((5RE2GT4FWH))))) If you didn’t ask for this code, or don’t know what this e-mail is about, you can safely ignore it.

How can such a simple replace not work? I thought that maybe the problem was that the two instances of {CODE} looked alike but were in fact composed of different characters, but I copy-pasted one over the other and it didn’t fix it.

Answer 1

You are invoking the replace() only on the last String object: ["If you didn't ask for this code, or don't know what this e-mail is about, you can safely ignore it."].

Store it [the final String, before the replace()] to some temp variable and retry, or use parentheses.
