Shape
Definition
Shape is a superclass in this context that serves as a blueprint for creating various types of shapes. It contains common attributes and methods related to shapes.
Analogy
Visualize shape as an abstract concept like "animal." Just like "animal" represents all living creatures, "shape" represents all possible geometric figures. It establishes a common ground for different types of shapes to inherit from.
Related terms
Circle: Circle is a subclass that extends the Shape superclass, inheriting its attributes and methods while adding specific properties related to circles.
Rectangle: Rectangle is another subclass that can extend the Shape superclass, inheriting its characteristics and defining additional features specific to rectangles.
Polymorphism: Polymorphism allows objects of different classes that share a common superclass to be treated as instances of the superclass, enabling flexibility in programming.

Consider the following superclass and subclass declarations: ```java public class Shape { private String color; public Shape(String color) { this.color = color; } public String getColor() { return color; } } public class Circle extends Shape { private double radius; public Circle(String color, double radius) { // Circle constructor implementation goes here } } ```
Given the block of code below, answer the following question: ```java class Shape { // constructor not shown public void draw() { System.out.println("Drawing a shape"); } } class Circle extends Shape { // constructor not shown @Override public void draw() { System.out.println("Drawing a circle"); } } ``` Question: Consider the code above. If we create an object of the Circle class and call the `draw()` method on that object, what will be the output?
