title: Decode Json urls
body: <p>I'm manually parsing Json objects using java and I have a problem with urls.</p>
  
  <p>They currently look like this:</p>
  
  <pre><code>http:\/\/a3.sphotos.ak.fbcdn.net\/hphotos-ak-ash4\/...
  </code></pre>
  
  <p>and I was wondering how to decode them into a normal form that I can further use, like this:</p>
  
  <pre><code>http://a3.sphotos.ak.fbcdn.net//hphotos-ak-ash4//...
  </code></pre>
  
  <p>It's not just the slashes that cause this problem, so simply searching for them is not a solution.
  I'm searching for a standard method from the jdk that could easily accomplish this.</p>
  
  <p>Unfortunately I have know idea what the encoding is called, so I can't be more specific in what I want to know.</p>
