Requirements / Prerequisites

A foundational understanding of core Java syntax, including variables, control structures (if/else, loops), and basic data types.
Familiarity with Object-Oriented Programming (OOP) principles such as classes, objects, inheritance, and interfaces is beneficial.
An eagerness to learn and adapt to new programming paradigms within the Java ecosystem.
A working Java Development Kit (JDK) installed on your machine (Java 8 or higher is recommended to follow along).
Access to an Integrated Development Environment (IDE) like IntelliJ IDEA, Eclipse, or VS Code for writing and running Java code.
No prior exposure to functional programming concepts or advanced Java features is necessary; this course starts with the essentials.
