Answer 1

1. Answer is abstract

In abstract class we can't instantiate objects. later we use this class methos in another class by using extending keyword.

2.Answer is implicit

If we assign one variable on type to another variable of different type it is known as implicit

An applications ability to select the correct subclass method is known as Dynamic method binding. It is is not known at compil time.

The perfect example for this is method over riding. Because eventhough different classes have same method the class object detemines which mehod to choose.
