title: How to parse JSON string without third-parties in JAVA
body: <p>I have following JSON response:</p>
  
  <p><a href="https://i.stack.imgur.com/q5RSs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/q5RSs.png" alt="enter image description here"></a></p>
  
  <p>It means server had exception.</p>
  
  <p>How can I parse any JSON string that I got from server for existence of exception without any third-parties?</p>
  
  <p>Once I determine that JSON contains exception I need to fetch code/message/status values.</p>
