for your first example, the only valid value for Consumer<?> is null, so
consumer.accept(null) should work.
for the second example, Consumer<? super String> accepts any subtypes of
String, given that String is final, the only possible type is String, so
consumer.accept(o.toString()) should work.
BTW, you may think that nobody will create voluntarily a BiConsumer<Consumer<? super
String >, Object>, and that's true, usually you get this kind of types as result of
method call inference,
e.g. you have a function g(f(Consumer<? super T>)) with T=String and g signature being
something like <E> BiConsumer<E, Object> g(E element).
Thanks for the detailed explanations!
OK - you have convinced me. I'll reluctantly withdraw my objection then ;-)
