How to make a nested Json object in Java?

Question

I want to program a nested JSON Object for my Android device, but how? I have only basic experience with Json, so I would appreciate if someone could help me with the following code:

{   "command": "login",  "uid": "123123123",  "params":   {    "username": "sup",    "password": "bros"   } } 

Edit:

The following code does solve the problem:

loginInformation = new ArrayList<NameValuePair>();   JSONObject parentData = new JSONObject(); JSONObject childData = new JSONObject();  try {      parentData.put("command", "login");     parentData.put("uid", UID.getDeviceId());      childData.put("username", username.getText().toString());     childData.put("password", password.getText().toString());     parentData.put("params", childData);  } catch (JSONException e) {     e.printStackTrace(); }  loginInformation.add(new BasicNameValuePair("content", parentData.toString()));

You need to create a JSON, and add that JSON as a parameter in your POST. To do that you should probably :

post.add(new BasicNameValuePair("data",json.toString()); 

You could use org.json.JSONObject, it is included in the Android SDK.
