Say here I have an Java interface Eat:
public interface Eat {
default void eat(Meat meat) {}
@Deprecated
default void eat(Meat meat, Mood mood) {}
}
And I have an abstract class implements only one method in the interface:
public abstract class DogBase implements Eat {
@Override
public void eat(Meat meat) {}
}
And I have a class extends the abstract class:
public class Dog extends DogBase {
}
Then I found that in the unit test for Dog class, the deprecated method:
@Deprecated
default void eat(Meat meat, Mood mood) {}
defined in the interface Eat can be called by an object of Dog class.
Why is this possible? In my understanding, the abstract class DogBase only implements the non-deprecated method defined in the interface so that class Dog should not have the deprecated method.
