/**
 * An abstract class representing a generic keyboard. It provides a framework for handling key
 * presses and displaying the keyboard's status.
 * Special Characteristics:
 * - Abstract Class: This class is abstract and cannot be initiated on its own. It requires
 *   subclasses to provide implementations for the abstract method handleKeyPress, allowing
 *   for various keyboard layouts.
 * - Inheritance: Subclasses can inherit the display method, promoting code reuse and
 *   polymorphism. This enables subclasses possibly share or override functionality.
 *   In this case, the purpose of using abstract and inheritance is to prove that I can use these.
