Group work held in the first semester of the degree in systems engineering of ISEP, within the scope of the curricular unit of Algoritmia and Programming Final grade: 15

This project was developed in two iterations and the utterance was as follows.

The bakery Not Just Cakes has managed its sales based on a handwritten notebook. With the increasing demand for quality cakes, the business has been growing and the management decided to adopt information technology. The objective is to develop a computer application that records information related to sales and allows for obtaining some statistics based on it.

The cakes are only sold through three vendors, Ana, Beatriz and Cláudio. A sale is always associated with a type of cake (Normal or Vegan), the amount of cakes sold and the total value of the cakes. A salesperson can make multiple sales because he can visit multiple customers.

Implement a Java application that allows you to provide the following features:

1. Read the sales data made by the three sellers. Each sales record has the following information: Seller, type of cake, quantity, total sale amount. Example: Ana Vegan 5 100

2. Show the following statistics:

   • Percentage of sales by type of cake, Normal and Vegan;
   • Total amount of cakes sold;
   • Sellers and quantities of cakes that sold each type of cake, Normal and Vegan, presented by descending order of quantity;
   • The seller who made the sale with the highest value and its value;
   • Average amount of cakes per sale;
   • Average value per sale.

The implementation should only use simple data structures and control-of-flow structures.

The implementation must use indexed data structures (mono and multidimensional) and flow control structures. It should also simplify the reading of the code adopting a modular organization, through structuring by methods. Consider using the following data structures to store the information:

• Seller array;
• Cake type array;
• Array (matrix) amount of cakes and value.

Input data:

Statistics generated:

Percentage of sales by type of cake
=> Normal: 55%, Vegan 45%

Total amount of cakes sold
=> 90

Sellers and quantities of cakes that sold Normal-type cakes
=> Ana: 39, Beatriz: 26, Claudio: 11

Sellers and quantities of cakes that sold Vegan-type cakes
=> Claudio: 10, Ana: 3, Beatriz: 1

The seller who made the sale with the highest value and its value
=> Ana: €379

Average amount of cakes per sale
=> 4.5

Average value per sale
=> €39.30
