title: JSONArray constructor issue
body: <pre><code>{"balance":1000.21,"is_vip":true,"num":100,"name":"foo"}
  </code></pre>
  
  <p>This is my json string. I want to iterate each element and get my output as</p>
  
  <pre><code>1000
  true
  100
  foo
  </code></pre>
  
  <p>I tried creating JSONArray with the following syntax</p>
  
  <pre><code>  JSONArray jsonarr = new JSONArray(myString);
  </code></pre>
  
  <p>But the error thrown is</p>
  
  <pre><code> "The constructor JSONArray(String) is undefined"
  </code></pre>
  
  <p>So what can be the possible solution this?</p>
