…ed from Machine. 2. Created a Machine class containing the public abstract void doWork() and public abstract void stopWork() methods. 3.

It displays messages indicating that a specific machine has stopped working. 5. In the MainApp class, I created a Machine array with Truck, Bulldozer and Excavator and called the doWork() and stopWork() methods in a loop.
