body: <p>is there a way we can import a class under another name?
  Like if i have a class called javax.C and another class called java.C i can import javax.C under the name C1 and import java.C under the name C2.</p>
  
  <p>We can do something like this in C#:</p>
  
  <pre><code>using Sys=System;
  </code></pre>
  
  <p>or Vb:</p>
  
  <pre><code>Imports Sys=System
  </code></pre>
