Data Types in Java: 🚀

Java Data Types are the foundational building blocks of all Java programs. Whether you’re a complete beginner starting your coding journey or a student reviewing core concepts, this video provides a clear and comprehensive guide.

In this lesson, we break down exactly what data types are and why they are essential for memory allocation and effective coding.

*In this video, you'll learn:*

*Primitive Data Types:* Detailed explanations and examples for all 8 primitives: `byte`, `short`, `int`, `long`, `float`, `double`, `boolean`, and `char`.
*Non-Primitive (Reference) Data Types:* A clear introduction to *Strings**, **Arrays**, and **Classes* and how they differ from primitives.
*Memory and Size:* Understanding the size (in bytes) of each primitive type and its memory allocation.
*Best Practices:* When to use `float` vs. `double` and how to avoid common errors when declaring variables.
