Create a base class base with an abstract print() method that is overridden in a derived class derived. the overridden version of the method prints the value of an int variable defined in the derived class. at the point of definition of this variable, give it a nonzero value, say, 11. in the base class constructor, call this method. in create an object of the derived type, and then call its print() method. explain the results. (1 point) 5. create three interfaces (you choose their names), each with two methods (you choose their return types and signatures). inherit a new interface that combines the three, adding a new method. create a class by implementing the new interface and also inheriting from a concrete class. now write four methods, each of which takes one of the four interfaces as an argument. in create an object of your class and pass it to each of the methods.
