Questions

1. What is wrong with the following interface?

   public interface House {
       @Deprecated
       void open();
       void openFrontDoor();
       void openBackDoor();
   }
   

2. Consider this implementation of the House interface, shown in Question 1.

   public class MyHouse implements House {
       public void open() {}
       public void openFrontDoor() {}
       public void openBackDoor() {}
   }
   

   If you compile this program, the compiler complains that open has been deprecated (in the interface). What can you do to get rid of that warning?
