In this project I have tried to implement the design pattern, functional programming, and some other similar functions in addition to some of my general knowledge.
int setPrice = prices.stream().mapToInt(integer -> integer).sum();Well, as it is a simple project there is no way to save the data permanently, but still, it will be temporarily saved in a list while the program is running, so you can go to the menu and your product list will still be valid.
Suppose you are the salesperson of a supermarket, and you want to get a receipt with all the purchases, and their corresponding information such as: time, transaction id, the salesperson, which product it was, how many products were purchased and/or the total value of your purchases.
In addition, we have tried to use the functions previously learned in the old devcamp classes such as code optimization or object creation.
I am currently working on a recoding of this project, because I am learning swing, also now I can program better so I think I can improve the code
