Question

Is there a way in Java/J2ME to convert a string, such as:

to an internal Object representation of

Answer 1

You can do this easily with Google GSON.

Let's say you have a class called User with the fields user, width, and height and you want to convert the following json string to the User object.

{"name":"MyNode", "width":200, "height":100}

You can easily do so, without having to cast (keeping nimcap's comment in mind ;) ), with the following code:

Gson gson = new Gson(); 
final User user = gson.fromJson(jsonString, User.class);

Where jsonString is the above JSON String.
