Domain Driven Design

Problem #1 : Add a “IPad Pro” to a Cart

Note: Please do not model/use User class

Problem #2: Add a “Hero ink Pen” to a Cart

Problem #3: Add 2 qty of “ GM Cricket bat” to Cart.

Problem #4: Remove already added Item “IPad Pro”( with all quantities) from cart.

Problem #5: As a business User I would like to know which Products ( product name) were deleted from Cart.

Problem #6: As a business User, I would like to differentiate between two Carts.

• Two carts where items are same, equality on Carts should return false

  Cart cart1 = Cart()

  Cart cart2 = Cart()

  Item item1 = new ( Item(Product("Ipad"), 1)

  Item item2 = new ( Item(Product("Ipad"), 1)

  cart1.add(item1)

  cart2.add(item2)

  cart1.equals(cart2) should be false*

Problem #7: Add Price to product

Notes: Java.Util.Currency ==> Currency.getInstance("USD") new Product("Ipad Pro", new Price(...));

Problem #8 - As a Business User I would like price my product 10% below competitor price (competitor price is available for product) . Assume that HashMap of Competitor Product Name and price is available. Competitor name matches 1 to 1 with our Product Name

new Product( "name", Price(discountedPrice, "USD"))
new Product( "name", Price(10, "USD"))

Problem #9 Create Order( with Products) when Cart is checked out. Also Mark cart as checked out .
While Creating Order please do not use Item class but use Product class. Flatten out products in Item.

Problem #10 - Customer and Bank Account When Customer’s Address is updated, update her all Bank Accounts address as well. (example of invariant or business rules or consistency rules)

Customer is Entity Account Is Entity Customer has List of bank accounts Customer has Address Account has Address Address has one attribute called City Address is Value Object ---- customer.updateAddress(address)

Problem #11 - Calculate Total cost for the Order. Put shipping cost as per weight Total cost = cost of all products in order + (weightIngrams of each product *.01)
