-## Getting Started
-
-Welcome to the VS Code Java world. Here is a guideline to help you get started to write Java code in Visual Studio Code.
-
-## Folder Structure
-
-The workspace contains two folders by default, where:
-
-- `src`: the folder to maintain sources
-- `lib`: the folder to maintain dependencies
-
-Meanwhile, the compiled output files will be generated in the `bin` folder by default.
-
-> If you want to customize the folder structure, open `.vscode/settings.json` and update the related settings there.
-
-## Dependency Management
-
-The `JAVA PROJECTS` view allows you to manage your dependencies. More details can be found [here](https://github.com/microsoft/vscode-java-dependency#manage-dependencies).

-A POS needs to be created. A customer would come to the cashier and the cashier would take items from the cart and enter the item ids to the system. The system would ask the number of items to be purchased. The system would create a bill and add line items to it. At the end, the total should be calculated and the tax should be added. The system would ask to enter the amount of money the customer would give. The system should print the entire bill with the balance to be given back to the customer.
