The Cab Booking Application is designed to provide users with a convenient way to book different types of cabs, including Prime Sedan, Mini, and Auto. The application incorporates design patterns to enhance modularity, extensibility, and maintainability.

• User authentication with regular and subscription pricing strategies.
• Booking of Prime Sedan, Mini, and Auto vehicles.
• Different features available for each vehicle type.

The application leverages the following design patterns:

• Singleton Pattern: Ensures that there is only one instance of the BookingManager class to manage cab bookings.

• Abstract Factory Pattern: Provides an interface for creating families of related or dependent objects. Factories include PrimeSedanFactory, MiniFactory, and AutoFactory.

• Strategy Pattern: Defines a family of algorithms, encapsulates each algorithm, and makes them interchangeable. Strategies include pricing strategies (RegularPricing and SubscriptionPricingStratergy) and features strategies (ACStratergy, noFeaturesStratergy, wifiandACStratergy).

• Proxy Pattern: Acts as a surrogate or placeholder for another object to control access to it. The ProxySubscriber class is used to authenticate and apply pricing strategies based on the user's subscription status.
