Change keys in JSON String

Question

I have a JSON String, but I need to change the names of the keys. How can I do this? Is it possible to change them directly without parsing the JSON to a HashMap or something?

not the best way, but you can do jsonString.replaceAll("\"oldKey\"", "\"newKey\""); — StrekoZ

only via an ugly regex that might not be very successful -

{ "foo" : "bar", "bar" : "foo"}

is going to cause you problems.

I would parse to an object format (like hashmap as you suggest) - and then do your search and replace on that - I think that it will be much more accurate.

I don't beleave that a regex could work, because the key may also be an value. And the value should not be replaced.
