Learn how to use Exceptions: try, catch, finally, throw using Kotlin. This can be a good option for you to learn about how to use the exception. Another thing is that we are using the video that will allow us to use those in our code too.
So check out How to Exception Handing in Kotlin.
You can learn about do while loop here in the video. Also apart from that you should also learn how to run commandline programs in kotlin. That should get you started on how to execute the programs on the command line. So check out that as well. I'd recommend it because from there onwards you can easily execute the programs. This can be a good option for you to learn about it with Kotlin.
I also covered about how to use the Do loop in kotlin. So if you want to know how to use the loop then this is the video to watch out for there.
Apart from that there are things that you can do like learn how to create class in kotlin and also learn how to create variable in kotlin.
I hope you like the video. You can support me when you get yourself a Android T-shirt.
Do let me know your comments and suggestions.
