Public void insert (List list){ }, which objects can be added to the list inside the method insert()?

Question

Javed Khan · Answer

An instance of Object Class or any of its child classes.
But methods of objects will only be available and the object will be up-casted to Object.

Zabeer Sultan · Answer

This list can accept any objects and it's equivalent to a non-generic list in that sense.
While retrieving the objects it comes implicitly as Objects and any casting needs to be done manually if required.
