How to iterate over a JSONObject?

Question

I use a JSON library called JSONObject (I don\'t mind switching if I need to).

I know how to iterate over JSONArrays, but when I parse JSO

This is is another working solution to the problem:

public void test (){

    Map keyValueStore = new HasMap<>();
    Stack keyPath = new Stack();
    JSONObject json = new JSONObject("thisYourJsonObject");
    keyValueStore = getAllXpathAndValueFromJsonObject(json, keyValueStore, keyPath);
    for(Map.Entry map : keyValueStore.entrySet()) {
        System.out.println(map.getKey() + ":" + map.getValue());
    }   
}

public Map getAllXpathAndValueFromJsonObject(JSONObject json, Map keyValueStore, Stack keyPath) {
    Set jsonKeys = json.keySet();
    for (Object keyO : jsonKeys) {
        String key = (String) keyO;
        keyPath.push(key);
        Object object = json.get(key);

        if (object instanceof JSONObject) {
            getAllXpathAndValueFromJsonObject((JSONObject) object, keyValueStore, keyPath);
        }

        if (object instanceof JSONArray) {
            doJsonArray((JSONArray) object, keyPath, keyValueStore, json, key);
        }

        if (object instanceof String || object instanceof Boolean || object.equals(null)) {
            String keyStr = "";

            for (String keySub : keyPath) {
                keyStr += keySub + ".";
            }

            keyStr = keyStr.substring(0, keyStr.length() - 1);

            keyPath.pop();

            keyValueStore.put(keyStr, json.get(key).toString());
        }
    }

    if (keyPath.size() > 0) {
        keyPath.pop();
    }

    return keyValueStore;
}

public void doJsonArray(JSONArray object, Stack keyPath, Map keyValueStore, JSONObject json,
        String key) {
    JSONArray arr = (JSONArray) object;
    for (int i = 0; i < arr.length(); i++) {
        keyPath.push(Integer.toString(i));
        Object obj = arr.get(i);
        if (obj instanceof JSONObject) {
            getAllXpathAndValueFromJsonObject((JSONObject) obj, keyValueStore, keyPath);
        }

        if (obj instanceof JSONArray) {
            doJsonArray((JSONArray) obj, keyPath, keyValueStore, json, key);
        }

        if (obj instanceof String || obj instanceof Boolean || obj.equals(null)) {
            String keyStr = "";

            for (String keySub : keyPath) {
                keyStr += keySub + ".";
            }

            keyStr = keyStr.substring(0, keyStr.length() - 1);

            keyPath.pop();

            keyValueStore.put(keyStr , json.get(key).toString());
        }
    }
    if (keyPath.size() > 0) {
        keyPath.pop();
    }
}
