Solution 1

You have created object for an abstract class which is not possible in java. If you want you can create a reference variable for an abstract class.

The whole idea of an abstract class is that you cannot create an instance of it: you always create instances of classes which derive from it.

Think of an abstract class as a Car: You can drive a car, you can own a car, you can crash a car. But you don't build a car - you build a Ford Focus, or a Mercedes A250e - you build an instance of a derived class: a Car -> Ford -> Focus
Car is abstract, Ford is abstract derived from Car, Focus is concrete, derived from Ford.

You can build that because it supplies information that allows an actual instance of a car to be defined.
