Kotlin programming notes

I have started a series of notes on Programming in Kotlin.

Chapter 6: Inheritance and
Chapter 7: Generics

have been added to the series and completes the story on classes.

This is a first draft, so let me know what you think.

The materials can be found at: Kotlin programming notes.

Thanks in advance, Ken

Could you please change the font? Just use Open Sans, Source Sans Pro or even Arial, but please not Comic Sans. It is hard to read.
