Retrieving values from nested JSON Object

Question

I\'ve got JSON file, which I want to parse. The JSON file (\"myfile\") has format as follows:

{
    \"LanguageLevels\": {
        \"1\": \"Początkujący\",
           


        

Answer 1

To see all keys of Jsonobject use this

    String JSON = "{\"LanguageLevels\":{\"1\":\"Pocz\\u0105tkuj\\u0105cy\",\"2\":\"\\u015arednioZaawansowany\",\"3\":\"Zaawansowany\",\"4\":\"Ekspert\"}}\n";
    JSONObject obj = new JSONObject(JSON);
    Iterator iterator = obj.keys();
    String key = null;
    while (iterator.hasNext()) {
        key = (String) iterator.next();
        System.out.pritnln(key);
    }
