<p>What are the implications of importing a java package using <code>.*</code> versus specifying a package explicitly.  For example,</p>

<pre><code>import java.lang.annotation.Annotation;
</code></pre>

<p>instead of</p>

<pre><code>import java.lang.annotation.*;
</code></pre>

<p>Are there penalties at compile time or run time when using wild card?</p>
