title: How to read JSON variable that use number for its name, with GSON
body: <p>First, im a beginner in GSON so please bear with me.</p>
  
  <p>I tried to read a JSON from this url : </p>
  
  <p><code>https://gdata.youtube.com/feeds/api/videos?author=radityadika&amp;v=2&amp;alt=jsonc</code></p>
  
  <p>I succeed to read a String variable like "id", "data", "uploader", etc.</p>
  
  <p>However, how can i read the <code>content</code> (inside <code>items</code>)? I want to get the RTSP link (<code>content:1</code>) but my Java keep give me error because i cant name a variable with number, like :</p>
  
  <pre><code>String 1 = "asd";
  </code></pre>
  
  <p>Any help is appreciated, Thanks for your help</p>
