Create an abstract class Furniture.

Inside this abstract class create a common method called getCompanyName(); Provide the same company name, Ashley Furniture for all types of Furniture.

Now create an abstract method called computePrice() that returns the price as an int.

Finally create two concrete furniture classes : Sofa & CoffeeTable. Extend both these classes to the Furniture class. Now provide an implementation for computeprice() by returning $2000 for sofa and $500 for CoffeeTable and by overriding the getCompanyName to return super.getCompanyName.
