I guess it's this class

We can retrieve each object to see the values

JSONArray jsonArray = new JSONArray(jsonString);

for (int i = 0; i < jsonArray.length(); i++) {
    JSONObject object = jsonArray.getJSONObject(i);
    clave = object.getString("clave");        
}

You could do this:

Remove the array from the json object:

JSONObject json = //Mi objeto json
JSONArray jsonArray = (JSONArray) json.get("miObjeto");

// assuming you have it defined within another json or

JSONArray json = new JSONArray();

Iterate using forEach:

jsonArray.stream()
    .forEach(s -> {
            //ejecutar acciones aquí
        });
