迭代Hashmap并将值存储在变量中以供使用-IteratethroughaHashmapandstorevaluesinvariablesforuse

Hello I retrieved some data from a MySQL database and I stored this data in a Hashmap. I also have created a class which has the same variables as the Hashmap. I want to iterate through the Hashmap and store the values so I can use them for each object. Any ideas how to do it?

您好我从MySQL数据库中检索了一些数据,然后将这些数据存储在Hashmap中。我还创建了一个与Hashmap具有相同变量的类。我想迭代Hashmap并存储值,以便我可以为每个对象使用它们。有什么想法怎么做?

 public void updateJSONdata() {

cafebartablesList = new ArrayList>();  

JSONParser jParser = new JSONParser();

JSONObject json = jParser.getJSONFromUrl(READ_COMMENTS_URL);

try {

    cafebartables = json.getJSONArray(TAG_POSTS);


    for (int i = 0; i ();

        map.put(TAG_TABLE_ID, tableId);
        map.put(TAG_MARGIN_LEFT, tableMarginLeft);
        map.put(TAG_MARGIN_TOP, tableMarginTop);
        map.put(TAG_ISFREE, isFree);

        cafebartablesList.add(map);


    }

} catch (JSONException e) {
    e.printStackTrace();
}
}

public  void printMap() {
LoadMap ld = new LoadMap();

ld.execute();

}

public class LoadMap extends AsyncTask {

@Override
protected Boolean doInBackground(Void... arg0) {
    updateJSONdata();
    return null;
}

@Override
protected void onPostExecute(Boolean result) {
    super.onPostExecute(result);

}
}
}
