get paramterized type java reflection

Question

Is there anyway to get the inner type parameter of a field using reflection

For Ex:

public final class Main
{
        class A
        {
                public int aX;
                public String aS;
        }

        class B
        {
                public Set<A> bSet;
        }
        public static void main(String[] args)
        {
                Class clazz = B.class.getField("bSet").getType();
        }
};

Using the above I can only get "Set" is there anyway I could get A as well ? Thanks

Reflection can indeed deliver full parameterized types for fields (and classes, etc). It's only objects that have their types erased at runtime.

Call getGenericType instead of getType and start reading javadoc.
