Review Summary

Your solution is approved. You’ve correctly implemented the abstract Machine class with public abstract void doWork() and public abstract void stopWork(), and each concrete class (Truck, Bulldozer, Excavator) properly overrides these methods with clear English messages indicating start/stop actions. MainApp demonstrates polymorphism by creating a Machine[] containing all three machines and iterating to call doWork() and stopWork(), matching the task requirements. I didn’t find any critical issues or checklist violations that would block functionality. As a minor non-blocking suggestion, keep commit/PR messages descriptive to aid reviewers (e.g., “Implement Machine hierarchy and MainApp usage”). Nicely done—clean, clear, and compliant with the requirements.
