Я использовал следующие строки:

Код: Выделить всё

  JsonParser jsonParser = new JsonParser();
JsonObject linksObj =  jsonParser.parse(jsonReader).getAsJsonObject();
JsonArray linksArray = jsonParser.parse(linksObj.get("results").toString()).getAsJsonArray();

Но я получаю сообщение об ошибке:

Код: Выделить всё

Exception in thread "main" java.lang.NullPointerException
at parseResponse.main(parseResponse.java:35)

Когда я попытался удалить текст перед «результатами», мой код смог успешно проанализировать ответ JSON. Может ли кто-нибудь объяснить, как я могу справиться с этой проблемой. Программа должна иметь возможность извлекать элементы массива без удаления строк вручную, как это было при отладке.
