**Question:**Which of the following statement(s) is/are True about interfaces?**Options:**- **A:** Interfaces are not classes, but like abstract classes; they are a means through which polymorphism can be achieved.- **B:** Interfaces can extend other interfaces.- **C:** Interfaces are abstract classes and are a means through which polymorphism can be achieved.- **D:** Interfaces can extend classes.**Explanation:**- **Option A** suggests that interfaces, although not classes, function similarly to abstract classes in facilitating polymorphism.- **Option B** states that interfaces have the ability to extend other interfaces, indicating inheritance is possible among interfaces.- **Option C** incorrectly claims that interfaces are abstract classes, which they are not, but acknowledges their role in achieving polymorphism.- **Option D** incorrectly suggests that interfaces can extend classes, which is not true in many object-oriented programming languages, as interfaces are separate from class hierarchies.

A B с Interfaces are not classes, but like abstract classes; they are a means through which polymorphism can be achieved Interfaces can extend other interfaces Interfaces are abstract classes and are a means through which polymorphism can be achieved

Design and implement a set of classes that define a series of threedimensional geometric shapes. For each shape, store fundamental data about its size, and provide methods to access and modify the data. In addition, provide appropriate methods to compute each shape’s circumference, area, and volume. In your design, consider how shapes are related and thus where inheritance can be implemented. Create a driver class to instantiate several shapes of differing types and exercise the behavior you provided
When should you use an abstract class? Group of answer choices 1. All options are correct. 2. When two or more classes will share identical methods, so that they can be moved into the abstract class. 3. When you want to make an object that is not concrete, and instead is more of an idea. 4. When you have classes that will share method names, but can have different implementations. 5. There is no need for abstract classes. Instead, interfaces are a better programming choice.
