I have this kind of map Map<String, String> , As you can see there is a inner map “token” and inside this map, there is inner map “tokeninfo”:

{
  "id": "44f79d20f28a2ea505b1",
  "type": "ONE",
  "cardIssued": "AA",
  "token": {
    "token1": "dummy",
    "tokenInfo": {
      "aaa": "007"
    },
    "payment": {
      "name": "test",
      "paymentType": {
        "card": "ONE"
      },
      "paymentAcc": "123"
    },
  "isDelegated": false,
  "attemptId": "981631"
}

In addition, I have this method :

private static HashMap<String, Object> getReplace(Map<String, Object> message) {
    HashMap<String, Object> message = new HashMap<>(message);

    for (String mapKey : PARAMETERS_FOR_REPLACE) {
        message.computeIfPresent(mapKey,
                (key, value) -> REGEX_ANY_CHAR.matcher(String.valueOf(value)).replaceAll("$^%%$"));
    }
    return message;
} 

I need to replace the value of some keys, from the map and inner map. like :
cardIssued ( from the map)
token1 ( from the inner map of the token)
aaa from the inner map of token -> tokeninfo
the value can be in any inner map, not just on the token and tokeninfo

Is there a way to stream all the values to check if it is a map and then call the method and replace it?

final result should be :

    {
  "id": "44f79d20f28a2ea505b1",
  "type": "ONE",
  "cardIssued": "$^%%$",
  "token": {
    "token1": "$^%%$",
    "tokenInfo": {
      "aaa": "$^%%$"
    },
    "payment": {
      "name": "test",
      "paymentType": {
        "card": "ONE"
      },
      "paymentAcc": "123"
    },
  "isDelegated": false,
  "attemptId": "981631"
}

if I run this:

  Map<String, Object> newMessage = getReplace(messageMap.entrySet().stream()
            .collect(Collectors.toMap(Map.Entry::getKey, entry -> (Object) entry.getValue())));

The value will change only in the “top” map.
Is there a way to use stream and do it in all inner and inner “inner” maps?
