How Can I Simplify JSON String to Object Conversion in Java ME?

Simplify JSON string to object conversion in Java ME

In Java/J2ME, you want to convert a JSON string (such as {name :"MyNode", width:200, height:100}) is converted to the internal object representation of this string in one line of code. Current methods are too cumbersome, for example:

Object n = create("new");
setString(p, "name", "MyNode");
setInteger(p, "width", 200);
setInteger(p, "height", 100);

JSON library solution

To simplify this conversion process, you can take the help of a JSON library. It is recommended to use the JSON-Simple library, which is small in size and very suitable for J2ME.

How to use

You can use the JSON-Simple library to parse a JSON string into a Java object with the following line of code:

JSONObject json = (JSONObject)new JSONParser().parse("{\"name\":\"MyNode\", \"width\":200, \"height\":100}");

Then , you can access the object's properties using the get() method:

System.out.println("name=" + json.get("name"));
System.out.println("width=" + json.get("width"));
