How to convert List to List. I tried doing this by
List<Object> obj = (some initialization)
List<Dog> dog =(List<Dog>)obj;
So this throws an error
ERROR: Cannot cast from List<Object> to List<Dog>
Where
List<Object>
I get from the Hibernate Query
FROM DOG
The cast works if you use a List<?>
instead:
List<?> list = (some initialization);
List<Dog> dog = (List<Dog>)list;
If you got a List<Object>
you still can cast it to a List<Dog>
List<Object> list = (some initialization);
List<Dog> dog = (List)list;
Of course this should only be done when you are sure that the list really contains Dog
objects (e.g. as result value from your HQL query FROM Dog
).
