Java: Parsing the JSON file

Question

I have a Json file like this

{"Name":"Saaa","AppIcon":["ddd.jpg","Wallpaper.jpg","ddd.jpg"]}

I need to extract the AppIcon values. I'm using json simple lib to parse the json. The code snippet to parse the values is:

FileReader appIconReader = new FileReader("jsonpath.json");
JSONObject jsonIconObject = (JSONObject)jsonParser.parse(appIconReader);
System.out.println("APPLICATION ICON = "+jsonIconObject.get("AppIcon"));`

But the output what I'm getting is a single string:

["ddd.jpg","Wallpaper.jpg","ddd.jpg"]

I need to extract the individual values like this

ddd.jpg
Wallpaper.jpg
ddd.jpg

Not with the square brackets ([]) and double quotes ("") as I'm getting right now. How can I do that?

That's not valid JSON. Please update your question with the exact JSON you're dealing with. — Hot Licks

JSON.simple isn't very thoroughly documented, but it looks like if you want to deal with an array, you need to cast the object returned by .get():

JSONArray appIcon = (JSONArray)jsonIconObject.get("AppIcon");

A JSONArray appears to be a generic container you can iterate, e.g.:

Iterator<String> it = appIcon.iterator();
while (it.hasNext()) System.out.println(it.next());

you can try this one also and it is store value in list type :

 try {
        FileReader appIconReader = new FileReader("jsonpath.json");
        JSONObject jsonIconObject = (JSONObject)jsonParser.parse(appIconReader);
        JSONArray lan = jsonIconObject.get("AppIcon"));
        List<String> list = new ArrayList<String>();
        for(int i = 0; i < arr.length(); i++){
            list.add(lan.getJSONObject(i).getString("name"));
        }

    } catch (org.json.simple.parser.ParseException e) {
        e.printStackTrace();
    }
