            "width": 97,
            "height": 130

            "width": 56,
            "height": 75
          },
          {
            "type": "w",
            "url": "https://sun1-

15.userapi.com/c850424/v850424557/ee1x5/dx4c4pOL7Q.jpg",
            "width": 1620,
            "height": 2160
          }
          
        ],
        "text": "",
        "date": 1570167720,
        "lat": 46.3238,
        "long": 38.2321
      }
  }

How can I represent it as a string using java? because only in this format I can upload to the database

{"response":{"count":22687,"items":[{"id":457223263017,"album_id":-7,"owner_id":-89600892,"user_id":100,"sizes": [{"type":"m","url":"https://sun1-
90.userapi.com/c850424/v850424557/xxx/BJTxSEZNPg.jpg","width": 97,"height": 130},{"type": "s".........}}

kambulovd if you have not broken json and you are not going to throw anything out of it, then it is very simple

JsonParser parser = new JsonParser();
    JsonObject jsonObject = parser.parse(ваша строка)
        .getAsJsonObject();
    assertTrue(jsonObject.isJsonObject());
    String result = jsonObject.toString();
    System.err.println("Result: " + result);

and if you are going to throw something out, then use gson GsonBuilder and gson.stream.JsonWriter (to find out exactly how to describe exactly what you want to throw out)
