📖 About This Repo

This repo documents my learning path through Java fundamentals and beyond. It contains notes, exercises, and projects built while working through the language — from the basics all the way to writing real, meaningful programs.

Primary references:

• Java: The Complete Reference — Herbert Schildt
• Effective Java — Joshua Bloch

🛠️ Prerequisites

Before getting started, make sure you have:

• Java JDK 21 or higher installed

  • Download Java
  • Verify installation: java -version

• Git installed

  • Download Git

• A code editor or IDE (Optional but recommended):

  • IntelliJ IDEA (recommended)
  • VS Code
  • Eclipse

🚀 Getting Started

1. Clone the repository:

   git clone https://github.com/Ledev0/MJF.git
   cd MJF

2. Navigate to a chapter:

   cd CH1

3. Compile and run a project:

   javac SProjects/SimpleCalculator.java
   java SProjects.SimpleCalculator

Each chapter has its own README with detailed lessons and project descriptions.

📌 Project Types

SProjects — Small, focused projects built to practice specific Java concepts. Each project targets one core idea (e.g., OOP, Collections, Generics, Exceptions).

BProjects — Larger, more complete projects. These are real programs that could be expanded, improved, or eventually spun off into their own standalone repos.
