The Class object can give you the exact constructor object (with
argument foo):
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Class.html#getConstructor(java.lang.Class...)
and then you can call the newInstance(fooObject) method on the
constructor object to create object with parameter foo.
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/reflect/Constructor.html#newInstance(java.lang.Object...)
