title: JSONSimple Overwriting
body: <p>I am attempting to iterate through a hash map and create a json string from the values. Im using the JSONSimple library to do so.  I have the structure I want, but the values are being overwritten.  The structure I am ending up with is </p>
  
  <pre><code>{
     "new_id":{
        "coordinates_list":{
           "Coordinates: ":[
              "lat: 27.0",
              "lon: 28.0"
           ]
        },
        "t0vhf40cv86t":[
           "123"
        ]
     }
  }
  </code></pre>
  
  <p>But there should be additional values in the JSON. Only the last row of the hash map is being included.  Do I need to add another JSONObject that I write to?</p>
  
  <pre><code>JSONObject obj = new JSONObject(); // final json object written out
  
      double lat = 20.00; // test data
      double lon = 21.00; // test data
      for (Map.Entry&lt;String, List&lt;String&gt;&gt; entry : data.entrySet()){
          JSONObject childObj = new JSONObject();
          JSONObject coordObj = new JSONObject();
  
          JSONArray entities = new JSONArray();
          JSONArray coordinates = new JSONArray();
  
          String key = entry.getKey();
          List&lt;String&gt; values = data.get(key);
          for(String value : values){
              entities.add(value);
          }
          childObj.put(key,entities);
  
          // increments the test data 
          lat = lat +1;
          lon = lon + 1;
  
          coordinates.add("lat: " + lat);
          coordinates.add("lon: " + lon);
  
          coordObj.put("Coordinates: " ,coordinates);
  
          childObj.put("coordinate list ", coordObj);
  
          obj.put("new_id" , childObj);
  
      }
  </code></pre>
