how generic collections , list store objects of different types ? possible?

because collections , list replacement arraylist

the main advantage of generic collections can specify exact type want store in collection , don't need boxing.

  • you create generic collection of type object. more or less same above, can use extension methods exist ienumerable<t>.
  • you create generic collection of common interface, types want store, implement.
