Java Core Notes ☕📘

This repository contains technical articles and notes about Java language fundamentals (Java Core), focusing on concepts that truly matter in real-world Java development.

The goal is not to provide quick tips, but to build a solid understanding of the language: compiler rules, scope, inheritance, memory, collections, and other topics that help developers write correct, readable, and predictable code.
