Java Basics: Selection and Iteration

Code and run your first Java program in minutes without installing anything! This course is designed for learners with no coding experience, providing a solid foundation of not just Java, but core Computer Science topics that can be transferred to other languages. The modules in this course cover printing, operators, iteration (i.e., loops), and selection (i.e., conditionals). To allow for a truly hands-on, self-paced learning experience, this course is video-free. Assignments contain short explanations with images and runnable code examples with suggested edits to explore code examples further, building a deeper understanding by doing. You'll benefit from instant feedback from a variety of assessment items along the way, gently progressing from quick understanding checks (multiple choice, fill in the blank, and un-scrambling code blocks) to small, approachable coding exercises that take minutes instead of hours.

It would be much better if there were video tutorials to provide further clarification.

The tests at the end are way to precise. I would get questions wrong because i didnt add a space in between something that doesnt need a space and is done for cosmetic reason when writing code.
