FAQs
Do I need prior programming experience?
No prior experience is necessary. Part I of the course is designed to take you from absolute zero to understanding core programming logic. However, the pacing is rigorous.
Which IDE will we be using?
We will primarily use IntelliJ IDEA (Community Edition is fine). I will also briefly show how to compile and run code from the terminal to ensure you understand the underlying mechanics.
Is this course up-to-date with the latest Java versions?
Absolutely. While we cover the foundational mechanics that have existed since Java 8, Module 7 is entirely dedicated to the modern features introduced up to Java 21, including Records, Switch Expressions, and Pattern Matching.
Does this cover Spring Boot or Web Development?
This is a pure Core & Advanced Java programming masterclass. It is designed to give you an unbreakable foundation so that when you move on to frameworks like Spring Boot or Jakarta EE, you understand exactly what is happening under the hood.
