How do I extend Java classes by Reflection?
<p>I have two Strings:</p>

<pre><code>String a="org.test.A";
String b="org.test.B";
</code></pre>

<p>I get a class by Reflection</p>

<pre><code>Class aClass = Class.forName(a);
</code></pre>

<p>I want aClass extends b, like:</p>

<pre><code>Class okClass=aClass.extends(b);//how to implement this?
</code></pre>

<p>how to implement this?</p>

<p>how to get okClass?</p>

<p>thanks!</p>
