Getting all inner classes by reflection
<p>I have the following problem. I have this pretty class and now I want to get all the classes that extend that class (inner classes ) and fill 'classList' with it. ( in an automatic way of course )</p>

<pre><code>public abstract class CompoundReference {

    private static List&lt;Class&lt;? extends CompoundReference&gt;&gt; classList
            = new ArrayList&lt;Class&lt;? extends CompoundReference&gt;&gt;();


    @CompoundKey(gsType = User.class, dbType = UserDetailsMappings.class)
    public static class CUser extends CompoundReference {
    }

    @CompoundKey(gsType = Catalog.class, dbType = CatalogDetailsMappings.class)
    public static class CCatalog extends CompoundReference {
    }

    @CompoundKey(gsType = Product.class, dbType = ProductDetailsMappings.class)
    public static class CProduct extends CompoundReference {
    }

    @CompoundKey(gsType = Category.class)
    public static class CCategory extends CompoundReference {
    }

    @CompoundKey(gsType = Poll.class, dbType = PollDetailsMappings.class)
    public static class CPoll extends CompoundReference {
    }
    // much mroe inner classes
</code></pre>

<p>Some manual solution would be just to main such a static block , that is something that I dont want to do.</p>

<pre><code>  static {
        classList.addAll(Arrays.asList(CUser.class, CCatalog.class,
                CProduct.class, CCategory.class,
                CPoll.class, CComment.class, CWebPage.class,
                CReview.class, CPost.class, CMessage.class, CStory.class,CPicture.class));

    }
</code></pre>
