how to create Java getters and setters when object key is number

I cannot create Java Getters and Setters, because I got number(digit) for my Object Key. I will show you my API response. How can I achieve this without changing the API.

    {"api_status": true,
    "message": "",
     "data": {
        "0": {
          "id": "aaa",
          "name": "aaa",
          "address": "aaa",
          "category": "aaa",
          "open_24_hours": "aaa",
          "business_open": "",
          "business_close": "",
          "type": "0",
          "title": null,
          "latitude": "6.8729428",
          "longitude": "79.8689013",
          "city": "",
          "distance": "2.95555089735992"
           },
       "1": {
          "id": "bbb",
           "name": "bbb",
           "address": "bbb",
           "category": "bbb",
           "open_24_hours": "bbb",
           "business_open": "",
           "business_close": "",
           "type": "0",
           "title": null,
           "latitude": "6.8767581",
           "longitude": "79.8674747",
           "city": "",
           "distance": "2.915385898910569"
         },
   }
  }
