What problem were you attempting to solve?

• Organizing/managing items, quantities, pricing
• Seamless checkout integration
• Total Calculations

How does your design address the solution?

• Items are easily displayed, accessed, and removed
  • ArrayLists make access efficient
• Item quantity is tracked and prevents negative instances
  • Quantities can be updated dynamically
• Abstract Discount class w/ flexible subclasses
  • Allows for discount combos
  • Cart total can be updated dynamically
• Straightforward checkout integration
  • Discounts are applied and total is calculated
  • Cart total can be passed externally
• Separation of concerns and error handling
  • common errors are handled w/ each step
  • Ongoing maintenance is simplified

How did you address each of the SOLID principles?

All files

• Single Responsibility Principle
  • Each of our classes has a single and clear responsibility
• Open/Closed Principle
  • We have an abstract class called discount that is extendable without many modifications to itself Discount File
  • We also have a cart item class that could be extended to create specific items and it would not cause any issues CartItem file
• Liskov Substitution Principle
  • Our classes that use the abstract class of discount correctly implement its methods within expectation Discount File
• Interface Segregation Principle
  • Our discount class provides the methods needed and no more, allowing for flexibility Discount Class
• Dependency Inversion Principle
  • All our classes follow the principle by not enabling one class to be too dependant on the other

How would you improve on your solution?

• Support different payment methods
  • credit
  • debit
  • paypal
• Have a tax collection system
  • Include tax calculation based on consumers location
• Out of stock handling
  • Include a check with inventory to ensure that items in the cart are in stock
