Understanding Java Variables - Primitive and Reference Types

Learn about variables in Java through a hands-on coding tutorial that explains both primitive and reference data types. Explore practical examples demonstrating how to declare and use different variable types including integers, doubles, characters, booleans, and strings. Practice with real-world scenarios like storing prices, grades, names, and car details while understanding the fundamental differences between primitive values stored directly in memory and reference variables that point to heap memory locations. Follow along with complete code examples that showcase variable declaration, value assignment, and string concatenation in print statements.
