Abstract and Concrete Methods: Vehicle class

In this problem, you will create a program that defines an abstract class Vehicle with a concrete method startEngine() and an abstract method getType(), overrides getType() in subclasses Car and Bike, and displays vehicle-type messages to standard output based on the input.

Learning Objective: Understand difference between abstract and concrete methods

Combine common concrete methods in abstract class with abstract methods implemented in subclasses.
