将 JsonArray 添加到 JsonObject

今天我在谷歌上搜索了很多关于这个话题的信息.但我找不到它，我如何才能将JSONArray添加到JSONObject？

Because everytime I do this I get this error: Stackoverflow

        JSONObject fillBadkamerFormaatFromContentlet(Structure structure, String formaat) {
    JSONObject jsonObject = new JSONObject();
    JSONArray arr = new JSONArray();

    BadkamerFormaat badkamerFormaat = new BadkamerFormaat();
    BadkamerTegel badkamerTegel;
    List<Contentlet> contentlets = getContentletsByStructure(structure);
    badkamerFormaat.formaat = formaat;
    badkamerFormaat.tegels = new ArrayList<BadkamerTegel>();

    try {
        jsonObject.put("formaat", formaat); 
    } catch (JSONException e1) {
        throw new RuntimeException(e1);
    }

    for(Contentlet contentlet : contentlets) {
        badkamerTegel = new BadkamerTegel();
        badkamerTegel.naam = contentlet.getStringProperty(ParameterNames.toolBetegelVeldNaam);
        try {
            badkamerTegel.afbeeldingTegel = contentlet.getBinary(ParameterNames.toolBetegelVeldTegelAfbeelding).getPath();
            badkamerTegel.afbeeldingBadkamer = contentlet.getBinary(ParameterNames.toolBetegelVeldBadkamerAfbeelding).getCanonicalPath();
            arr.put(badkamerTegel.toJSON());
        } catch (IOException e) {
            throw new RuntimeException(e);
        }   
    }

    try {
        jsonObject.put("aoColumnDefs",arr);
    } catch (JSONException e) {
        throw new RuntimeException(e);
    }

    return jsonObject;          
}

I get this error:

The JSON I want: Only the last JsonArray is going wrong:

{
           "wand": [
        {
            formaat: 'vierkant15x15'
            tegels: [
                    {naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ,{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ]
        }
        ,

        {
            formaat: 'vierkant17x15'
            tegels: [
                    {naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ,{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ]
        }
    ]

, "vloer": [ { formaat: 'vierkant10x15' tegels: [ {naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'} ,{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'} ] } ,

        {
            formaat: 'vierkant45x15'
            tegels: [
                    {naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ,{naam: '', imgThumb: '/bla/bla.png', largeImg: '/bla/bla2.png'}
                    ]
        }
    ]
