• Create class core.basesyntax.Machine containing methods public abstract void doWork() and public abstract void stopWork().
• Create classes core.basesyntax.Truck, core.basesyntax.Bulldozer, and core.basesyntax.Excavator that will inherit from core.basesyntax.Machine.
• In those classes override doWork(), so it will print a message that a certain machine started its work.
• Override stopWork() as well. It should print messages that certain machines stopped working.
• In the MainApp class create a core.basesyntax.Machine array with core.basesyntax.Truck, core.basesyntax.Bulldozer, and core.basesyntax.Excavator and call methods doWork() and stopWork() in a loop.
