is using import some.directory.* worse for performance?
<p>What is better for performance using </p>

<pre><code>import some.directory.*; 
</code></pre>

<p>or </p>

<pre><code> import some.directory.classNeeded;
</code></pre>

<p>Or does this not make any change on performance as the compiler discounts libraries that aren't used with in the class? So it was implemented for convenience?</p>
