Using GSON to parse a JSON array

I have a JSON file like this:

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

Before when files had a root element I would use:

Wrapper w = gson.fromJson(JSONSTRING, Wrapper.class);

code but I can't think how to code the Wrapper class as the root element is an array.

I have tried using:

Wrapper[] wrapper = gson.fromJson(jsonLine, Wrapper[].class);

with:

public class Wrapper{

	String number;
	String title;
	
}

But haven't had any luck. How else can I read this using this method?

P.S I have got this to work using:

JsonArray entries = (JsonArray) new JsonParser().parse(jsonLine);
String title = ((JsonObject)entries.get(0)).get("title");

But I would prefer to know how to do it (if possible) with both methods.

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.

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"    }]

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);

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