Java Generics Type Casting -

lets say...

<t, s extends t> void work(final class<t> type, final s object) {} 

or

<t> void work(final class<t> type, final t object) {} 

how can pass following parameters work()?

final class<?> type = <not null> // reflection output. final object object = <not null>  assert type.isinstance(object); // absolutely guaranteed  work(type, type.cast(object)); // compile error; how can this? work(type, object); // compile error; how can this? 

you'd need class<t> work, can that. once have that, can this:

work(type, type.cast(object)); 

now, since you've got class<?> can't assign class<t>, can work around providing additional method:

<t> void checkedwork(final class<t> type, final object object) {     work(type, type.cast(object)); }
