For what you want to do you don't need to use a regex!

You can make use of the replace method instead to match specific chars, which increases readability a bit:

String regex = getData.replace("{", "").replace("}", "");

Escaping the \\{ just to be able to use replaceAll works, but doesn't make sense in your case

Curly brackets are used to specify repetition in regex's, therefore you will have to escape them.

Furthermore, you should also consider removing all the brackets in one go, instead of called replaceAll(String, String) twice.

String regex = getData.replaceAll("\\{|\\}", "");

You need to escape {:

String regex = getData.replaceAll("\\{", "").replaceAll("\\}", "");
