Subject: [PATCH 1/3] - Created abstract class Machine and abstract methods for
 this class doWork(), stopWork() - Created new classes: Bulldozer, Excavator,
 Truck and extended them from the superclass Machine - Overridden methods:
 doWork() and stopWork() for each subclass - updated class MainApp:   - added
 new Machine array with Truck, Bulldozer and Excavator and call methods
 doWork() and stopWork() in a loop
