title: Convert a JSON String to a HashMap
body: <p>I'm using Java, and I have a String which is JSON:</p>
  
  <pre><code>{
  "name" : "abc" ,
  "email id " : ["abc@gmail.com","def@gmail.com","ghi@gmail.com"]
  }
  </code></pre>
  
  <p>Then my Map in Java:</p>
  
  <pre><code>Map&lt;String, Object&gt; retMap = new HashMap&lt;String, Object&gt;();
  </code></pre>
  
  <p>I want to store all the data from the JSONObject in that HashMap.</p>
  
  <p>Can anyone provide code for this?  I want to use the <code>org.json</code> library.</p>
