## Workflow
- git checkout <dein_branch> (branch wechsel)
- git branch (zeigt alle branches)

1. Pull
- git pull
3. Create Branch
- git checkout -b <dein_branch>
5. Test und development Prozess
6. Merge Master auf Featurebranch
1. git checkout Develop
2. git pull
3. git checkout <dein_branch>
4. git merge Develop
5. conflicts lösen
6. run test
7. git push
7. Merge Request auf Master
8. Review Prozess
9. Merge auf Master

    // Date für mhd erzeugen
    Date date = new Date(int year, int month, int date);
    // JSONObject erzeugen
    JSONObject food = new JSONObject();
        try {
            food.put("id", );
            food.put("barcode", 12368325);
            food.put("name", "Arthur");
            food.put("amount", 5);
            food.put("mhd", date);
            food.put("restock", true)
        } catch (JSONException e) {
  
    JSONArray jArr = new JSONArray();
    jArr.put(food);
    
    //get Data from jsonArray
    for (int i=0; i < jArr.length(); i++) {
        JSONObject obj = jArr.getJSONObject(i);
        long id = obj.getLong("id");
        long barcode = obj.getLong("barcode");
        String name = obj.getString("name");
        int amaount = obj.getInteger("amount");
        Date mhd = obj.getDate("mhd");
        boolean restock = obj.getBoolean("restock");
    }
