+/**
+ * Answers the question.
+ *
+ * Question3:
+ *
+ * - Q: What is the problem with the resize method of the Shape calss? How do
+ * you solve this problem?
+ *
+ * - A: The resize method of the Dot class is inherited from the Shape class.
+ * which does not have a throw Exception declared. We can solve this problem by
+ * declaring the resize method in the Shape class as a throw Exception.
+ *
+ * - Q: Do you need to change the resize method of the Circle class then?
+ *
+ * - A: No, we do not need to change the resize method of the Circle class.
+ *
+ * - Q: Does the Square class need its own area and resize method or not?
+ *
+ * - A: No, but it depends. Currently the Square.area and Square.resize methods
+ * return the correct values. But in the future, if we want to change the
+ * Rectangle.area and Rectangle.resize methods, the Square class may give the
+ * wrong values. So it is better to have its own area and resize methods.
+ *
+ * - Q: What is then the problem for the Square class?
+ *
+ * - A: No problem. The area method is overloaded. But the resize method in
+ * Square can set different values for the width and height. So it is better to
+ * have its own resize methods.
