Issue with parsing the content from JSON file with Jackson & message- JsonMappingException -Cannot deserialize as out of START_ARRAY token

JsonMappingException: out of START_ARRAY token exception is thrown by Jackson object mapper as it's expecting an Object {} whereas it found an Array [{}] in response.

This can be solved by replacing Object with Object[] in the argument for geForObject("url",Object[].class). References:

Your JSON string is malformed: the type of center is an array of invalid objects. Replace [ and ] with { and } in the JSON string around longitude and latitude so they will be objects:

[    {        "name" : "New York",        "number" : "732921",        "center" : {                "latitude" : 38.895111,                 "longitude" : -77.036667            }    },    {        "name" : "San Francisco",        "number" : "298732",        "center" : {                "latitude" : 37.783333,                 "longitude" : -122.416667            }    }]

I sorted this problem as verifying the json from JSONLint.com and then, correcting it. And this is code for the same.

String jsonStr = "[{\r\n" + "\"name\":\"New York\",\r\n" + "\"number\": \"732921\",\r\n"+ "\"center\": {\r\n" + "\"latitude\": 38.895111,\r\n"  + " \"longitude\": -77.036667\r\n" + "}\r\n" + "},\r\n" + " {\r\n"+ "\"name\": \"San Francisco\",\r\n" +\"number\":\"298732\",\r\n"+ "\"center\": {\r\n" + "    \"latitude\": 37.783333,\r\n"+ "\"longitude\": -122.416667\r\n" + "}\r\n" + "}\r\n" + "]";ObjectMapper mapper = new ObjectMapper();MyPojo[] jsonObj = mapper.readValue(jsonStr, MyPojo[].class);for (MyPojo itr : jsonObj) {    System.out.println("Val of name is: " + itr.getName());    System.out.println("Val of number is: " + itr.getNumber());    System.out.println("Val of latitude is: " +         itr.getCenter().getLatitude());    System.out.println("Val of longitude is: " +         itr.getCenter().getLongitude() + "\n");}

Note: MyPojo[].class is the class having getter and setter of json properties.

Result:

Val of name is: New YorkVal of number is: 732921Val of latitude is: 38.895111Val of longitude is: -77.036667Val of name is: San FranciscoVal of number is: 298732Val of latitude is: 37.783333Val of longitude is: -122.416667
