Universal Stock Management

This project implements a basic stock management system in Java. It allows you to add, remove, search, and edit product and supplier information.

File Structure

• Product.java: This file defines the Product class, which represents a product in the stock. It includes attributes such as name, code, unit type, price per unit, amount in stock, and supplier information.
• Stock.java: This file defines the Stock class, which manages the collection of products and suppliers. It provides methods for adding, removing, searching, and sorting products and suppliers.
• Supplier.java: This file defines the Supplier class, which represents a supplier of products for the stock. It includes attributes such as name, address, CNPJ (Brazilian national certificate of legal entity), and code.
• Main.java: This file is the main application class. It creates the user interface, interacts with the Stock class to manage products and suppliers, and handles data persistence using file I/O.
• ProductDescription.java: This file defines the ProductDescription class, which creates a window to display detailed information about a selected product.
• SuppliersPanel.java: This file defines the SuppliersPanel class, which creates a window to manage suppliers. It allows adding, removing, searching, and sorting suppliers.

Dependencies

This project uses the following libraries:

• Java Swing for the graphical user interface

Running the application

1. Compile the Java source files using a Java compiler. You can use a command like javac -cp .:./lib/* Main.java Product.java Stock.java Supplier.java ProductDescription.java SuppliersPanel.java (assuming the libraries are in a lib folder).
2. Run the application using the java command: java -cp .:./lib/* Main

Features

• Add, remove, search, and edit product information (name, code, unit type, price per unit, amount in stock, and supplier)
• Add, remove, search, and edit supplier information (name, address, CNPJ, and code)
• Sort products and suppliers by name or code
• Auto-generate product codes
• Load and save stock data from a file (file.bin)

Additional Notes

• The CNPJ attribute in the Supplier class is specific to Brazil. You can modify it to fit the supplier identification standard in your region.
• The application uses a basic file I/O approach to store data persistently. Consider using a database for larger-scale applications.
