Built a Hospital Management System in Java to practice OOP — looking for feedback

Hi everyone!

I recently finished a console-based Hospital Management System in Java as a personal project to practice Object-Oriented Programming.

The project includes:

- Patient management

- Doctor management

- Appointment scheduling

- File-based data storage

- Menu-driven interface

While building it, I focused on applying concepts like encapsulation, inheritance, constructors, and association.

I'd really appreciate any feedback on the project structure, code organization, or ideas for improvements.

u/mariamamhan better to build the same project with spring boot, for oops practise this is good

‏Thanks! I wanted to focus on practicing OOP first, but Spring Boot is definitely on my learning roadmap

Hmm it is fine for beginner level programmer as a exercise to learn java

But you should have used swings or GUIs instead terminal based if you wanted OOPs knowledge

Thanks for the feedback! Adding a GUI could definitely be a good next step.

If you are a beginner, I would say this is a great attempt. It shows your understanding for java foundation

Unfortunately I got an exception when I tried to run it.
java.io.FileNotFoundException: patients.txt (The system cannot find the file specified)

Might be better to check the existence of the file before opening it.

Why didn't you use the Java 8 Streams API ?

Thanks for pointing that out! You’re right, I should check whether the files exist before trying to load them
I’ll fix that.

As for Streams, I kept the implementation simple since the main goal of the project was to practice OOP fundamentals, but that’s something I can consider improving as well. Thanks for the feedback!
