Matrixnator: A Simple Java Matrix Printing API

A lightweight and clean Java library for elegantly printing formatted matrices to the console. The goal of Matrixnator is to provide a reusable and DRY (Don't Repeat Yourself) API for visualizing two-dimensional data structures in a clear way, aiding in application development and debugging.

This project was created as part of my Java studies and personal growth as a developer.

Highlights 🚀

• Matrix Printing: Native support for float, double, and int matrices.
• Centered Alignment: All values are automatically centered within their cells for a professional aesthetic.
• Grid Structure: Uses Unicode characters to draw borders and grids, providing a clear visual representation of the matrix structure.
• Simple API: The API interface is intuitive and straightforward, consisting of static methods that require no instantiation.
• Robust Error Handling: Handles null or empty matrices gracefully, preventing NullPointerException and providing informative messages.
• Method: this project was made with the help of Gemini 2.5 Flash, so it could help me on my Java studies!
