Показать описание
Welcome to Lecture 2‑2 of our Java Programming series in 2025.
In this session, we’ll switch from theory to practical coding. You will learn how to use primitive data types like int, long, char, double, and boolean in real Java programs.
This hands-on tutorial is perfect for Java beginners looking to understand variables through practical examples.
What you'll learn in this video:
How to declare and use primitive variables in Java
Difference between int and long
Using char and boolean effectively
When to use double vs int
Make sure to watch Lecture 2‑1 for the theory part before continuing with this coding session.
