Level Up Your Java Skills

Heard about object-oriented programming, but not sure what it is?

Object-oriented programming (OOP) is a popular style of programming. It comes up in technical interviews often and it's an essential skill for every developer.

The problem is that there’s lots of bad info out there about OOP. Lots of myths, misconceptions, bad advice and downright poor tutorials and books. It took me a long time to really get it!

That’s why I've designed this course for you.

No fluff, no jargons, no over-complicated descriptions.

Clear, concise, practical OOP using real-world examples, exercises and step-by-step solutions.

@moshhamedani I just finished your Java Fundamentals course. You explained so many details that my classes sort of glossed over. The debugger has been demystified. Great course and resource! #Java
