Editor's Notes
- You’ll be working through Kotlin Koans, a set of interactive exercises on the Kotlin language website. These exercises will help you ramp up quickly on language syntax and important aspects of the Kotlin language. If you’re wondering, what is a Koan? It’s a paradoxical riddle or puzzle. So Kotlin Koans is a fun play on words!
- To give you a brief tour of the interface, on the left-hand side, you’ll see the categories of exercises that you’ll work through. For this session together, work through the first 3 categories: Introduction, Conventions, Collections. Exercises in the later categories Properties, Builders, and Generics are optional. You can do them on your own time if you’d like.
- Once you click into a category and click into an exercise, the instructions for that exercise will appear on the right hand side. You’ll be typing your code in the middle. Some starter code will already be provided for you and you will type your answer in the places marked TODO(). When you think you have your answer, click the blue play button. Some unit tests will be run to verify your code. The output of these tests will show below your code. If you get stuck or want to start over with the original code provided in an exercise, click the Revert button. As you’re working, you can call me over if you have questions. If you truly get stuck, there is an option to Show answer, but use that as a last resort since you’ll remember the concepts much better if you can solve the Koan without looking at the answer.
- If you click the black “Play” button in the top menu bar, you will open the Kotlin Playground, which is another helpful tool. This allows you to practice writing and running Kotlin code, all within a web browser without needing to install an IDE.
- Start by opening up the landing page for Android Study Jams. You will automatically be awarded this badge for being a participant Android Study Jams! Save it to your developer profile, and create a profile if you haven’t already.
- All the badges that you earn in this track will be saved there.
- As a reminder, in this session, you’ll work on the Kotlin Koans only in these first 3 categories, as shown in the slide. Introduction Conventions Collections Go ahead and start by going to this link. We will be taking a break at <Insert Time>. I’ll leave these tips up for what to do if you’re stuck. Or as always, I’m available to help if needed. [Mention other facilitators if those are available.] [Leave this up as people work. You can let them work for about 45 minutes and then take a break.]
