Java Technical Evaluaiton for Thaddeus Tuck

Overview:

This exercise is designed as a general evaluation of an applicant's experience with Java and building/consuming webservices. In this project you will be writing two deliverables for a small book store.

Deliverable #1:

• Using the services provided, write a RESTful service to calculate the total quantities and valuation of the book store's inventory. (You'll use this service in the second deliverable)
  • Invoke the inventory RESTful service to get the list of items and quantities.
  • Invoke the book RESTful service to get the list of books and prices.
  • Results should contain quantities and values per upc, in addition to a total inventory valuation as JSON
  • JAR files for each service are provided and may be ran with java -jar <filename> --server.port={server-port}
  • Documentation for each service is provided by Swagger (http://localhost:{server-port}/swagger-ui.html#/)

Deliverable #2:

• Write a command line application that can process a given list of sales from consumers and shipments from suppliers.
  • Post sales and shipment quantity adjustments to the inventory service.
    • Sales should decrease the available inventory
    • Shipments will increase the available inventory
  • Track total sales per item, and total sales across all items using data provided by the book service.
  • Retrieve financial inventory data from the service you wrote. (see deliverable #1)
  • Output the starting inventory amounts/valuation, total daily sales, and final inventory amounts/valuation to a results.txt file.
    • Total inventory valuation is the sum of all valuations for each upc (and a upc's valuation is its quantity multiplied by its selling price point)
  • Sales and shipments will be provided via flat file representing a single day (eg 2019-12-01.txt will represent the shipments and sales for December 1st 2019), as an argument to the program (see block below for example)

  # SALE|{upc}|{qty}
  # SHIPMENT|{upc}|{qty}
  SALE|1|3
  SHIPMENT|1|10
  SALE|2|4
  ...
