title: What is "java web start" used for?
body: <p>I was reading about java web start from <a href="http://en.wikipedia.org/wiki/Java_Web_Start" rel="noreferrer">wiki</a>. Can someone please tell me</p>
  
  <ul>
  <li>What is it used for?</li>
  <li>A practical application of it; to make its use clearer.</li>
  <li>Do other languages like C++ / C# have
  anything similar?</li>
  </ul>
  
  <p>Thanks,<br>
  Roger</p>
