There is a redundant empty line after the package declaration. This violates checklist item: "Please don't add redundant empty lines to your code."

@Override
public void doWork(){
System.out.println("Bulldozer started work");
};

There is a redundant semicolon after the closing brace of the doWork() method. While this does not break functionality, it is unnecessary and should be removed for cleaner code.

@Override
public void stopWork(){
System.out.println("Bulldozer stopped work");
}
