Harshal Parekh :
I have a JSONObject (org.json) like this:
{
"a": "a",
"b": "a",
"c": "a",
"d": "a",
"e": "a",
"f": "a",
"g": "a",
...
}
I would like to remove all the keys except a. Is there an elegant way to do this other than my naive approach?
Iterator<String> keys = jsonObject.keys();
while (keys.hasNext()) {
if (!keys.next().equals("a")) {
keys.remove();
}
}
Expected output:
{"a": "a"}
Naman :
I believe a simpler way to do that would be using removeIf as
jsonObject.keySet().removeIf(k -> !k.equals("a"));
