public interface Guard
{
    void doYourJob();
}

abstract public class Dog implements Guard {}
Which of the following statements is correct?


This code will not compile, because method doYourJob()
in interface Guard must be defined abstract.
This code will not compile, because class Dog
must implement method doYourJob() from interface Guard.
This code will not compile, because in the declaration of class
Dog we must use the keyword extends instead of implements.
This code will compile without any errors.
