Now that I’m slowly familiarizing myself in the world of Python, I am much more often confronted with classes and object-oriented programming (OOP). While R has its own OOP paradigms (yes, multiple, obviously, it’s R after all), I have never experienced the need to create my own classes. However, in other languages, like Python, Ruby, or Java, OOP is much more an essential of developers’ and programmers’ skillsets.
Now, I personally won’t start on learning Java anytime soon. Hence, I am just sharing this pearl of a resource with a wider audience right now. This MOOC by the university of Helsinki has been in my inbox for quite a while: Object-Oriented Programming with Java. If you understand Finnish, you can even take the 2019 Finnish version of the course.
During this course you will learn all the basics of computer programming, algorithms and object-oriented programming using the Java programming language. The course includes comprehensive course materials and plenty of programming exercises, each tested using our automatic testing service Test My Code.
Part 1 of the course will teach you all the basics of the Java language:
Part 2 continues with some more advanced topics:
While I have not taken the course myself yet, I have read a lot of good reviews about it. Moreover, what better way to learn a new language than by deep diving into it with a specialized topic like OOP. And it’s free! And taught by trained academics! What are you still doing here, start learning!
