Using GSON to parse a JSON array


java arrays json gson

Problem is caused by comma at the end of (in your case each) JSON object placed in the array: 

{    "number": "...",    "title": ".." ,  //<- see that comma?}

If you remove them your data will become

[    {        "number": "3",        "title": "hello_world"    }, {        "number": "2",        "title": "hello_world"    }]

and 

Wrapper[] data = gson.fromJson(jElement, Wrapper[].class);

should work fine.

java arrays json gson 

Gson gson = new Gson();Wrapper[] arr = gson.fromJson(str, Wrapper[].class);class Wrapper{    int number;    String title;       }

Seems to work fine. But there is an extra , Comma in your string.

[    {         "number" : "3",        "title" : "hello_world"    },    {         "number" : "2",        "title" : "hello_world"    }]

java arrays json gson 

public static <T> List<T> toList(String json, Class<T> clazz) {    if (null == json) {        return null;    }    Gson gson = new Gson();    return gson.fromJson(json, new TypeToken<T>(){}.getType());}

sample call:

List<Specifications> objects = GsonUtils.toList(products, Specifications.class);
