title: Java String reorder
body: <p>I have a string like this format</p>
  
  <p>Number. Subject, Uni Name, Location 2</p>
  
  <p>I want to re-order the format like this one</p>
  
  <pre><code>Number. Uni Name, Subject, Location 2
  </code></pre>
  
  <p>I can do the operation by this way</p>
  
  <pre><code>int index = Order .indexOf(",");
  String newStr =Order .substring(index + 1, Order .length());
  </code></pre>
  
  <p>But,I think all string have a different name and length, so may be this will not work. So, my question is how can re-order the string format dynamically with a efficient way ?</p>
