title: How to get String from JSONObject without Specific Name
body: <p>Please check this code sample.</p>
  
  <pre><code>HttpEntity getResponseEntity = getResponse.getEntity();
  
  String message = EntityUtils.toString(getResponseEntity,"UTF-8");
  
  //message = {"EntryPointJsonResult":"{\"NextTransactionUrl\":null,\"TraceId\":null,\"IsAuthorizationRequired\":false,\"IsError\":false,\"ErrorCode\":null,\"ErrorMessage\":null}"}
  
  JSONObject object = new JSONObject(message);
  String objectString = object.getString("EntryPointJsonResult"); 
  //objectString = {\"NextTransactionUrl\":null,\"TraceId\":null,\"IsAuthorizationRequired\":false,\"IsError\":false,\"ErrorCode\":null,\"ErrorMessage\":null}               
  </code></pre>
  
  <p>That's the question : I want to get the "objectString"  without "EntryPointJsonResult". Cause this information is different at the another response. </p>
  
  <p>So how can I get the "objectString" without specific key like "EntryPointJsonResult"</p>
