Free Pack

Free Introductory Level — Getting Started with Java

Free Pack is a completely free starter package designed specifically for people taking their very first steps in Java programming or wanting to quickly check if this language feels right for them. It avoids heavy theory and doesn’t try to cover everything at once — it focuses only on the essentials so that within 2–4 hours you can write, compile, and run your very first program, understand what variables are, and learn how to output information to the screen.

The package consists of three short but clear modules:

• Module 1: First Program Installing JDK, setting up the environment (VS Code or IntelliJ IDEA Community), creating a .java file, writing the classic Hello World, compiling with javac and running with java, explaining program structure and common beginner mistakes.
• Module 2: Variables and Data Types Main primitive types (int, double, boolean, char), strings (String), variable declaration and initialization, naming rules, simple assignment and arithmetic operations, first experiments with overflow and type conversion.
• Module 3: Simple Screen Output Difference between print and println, string concatenation (+), basic formatting with printf, outputting variable values, escape sequences (\n, \t, \”), creating simple messages with data.

All material is built around practical examples and short exercises you can complete right after each module. You will receive ready code files for review and a template for your own practice. After finishing Free Pack, you will confidently know how to run Java programs on your computer and understand the basic “language” of a program — the perfect foundation to decide whether to continue along the Bytecodejic path (Align Series and beyond).

This is not just a “try for free” gimmick — it is a complete first step that gives you real skills and confidence.
