Explanation:
• In this program, we have a superclass Shape and a subclass Circle.
• The Shape class has an attribute color, and a method displayColor() to display the color.
• The Circle class extends the Shape class and adds its own attribute radius and a method displayRadius()
to display the radius.
• In the Circle constructor, super(color) is used to call the superclass constructor and initialize the inherited
attribute.
• In the main method, we create an instance of the Circle class with a color and radius, and call the displayColor()
and displayRadius() methods.
These examples demonstrate how superclasses and subclasses are used in Java to create hierarchical
relationships, promote code reusability, and achieve inheritance. The subclass inherits attributes and methods
from its superclass and can also add its own unique attributes and behaviors. This allows for code organization
and simplifies the maintenance and extension of software systems.
