<pre class="prettyprint"><code>private final Class<? extends FragmentActivity> activityClass; </code></pre> I understand the definition except for the <code><? ></code> part. Is there some reason for the extends to be enclosed in that special text?

that is wild card character that says any it can take any type which <code>extends</code> <code>FragmentActivity</code>

Is there some special meaning to the text "<? >"?

private final Class<? extends FragmentActivity> activityClass;

I understand the definition except for the <? > part.

Is there some reason for the extends to be enclosed in that special text?
