This is the repository for the LinkedIn Learning course Kotlin Essential Training: Functions, Collections, and I/O. The full course is available from LinkedIn Learning.

If you’re looking to get up and running with Kotlin, the powerful programming language from JetBrains, this course gives you the tools you need to start writing command-line programs in a matter of hours. Join instructor Nate Ebel, the author of Mastering Kotlin, as he shows you the ins and out of Kotlin and walks you through its unique selling points for developers—from null safety and concise syntax to Java compatibility, to full support by Google for Android development.

Get a comprehensive overview of writing code in Kotlin, including the basics of data types, variables, statements, expressions, functions, and classes. Learn how to use the essential features of this powerful, interoperable language as well as effectively debug your code. Along the way, Nate gives you expert pointers on how to write safe and efficient multithreaded code using Kotlin coroutines to manage multiple tasks at the same time.

This repository has branches for each of the videos in the course. You can use the branch pop up menu in github to switch to a specific branch and take a look at the course at that stage, or you can add /tree/BRANCH_NAME to the URL to go to the branch you want to access.

The branches are structured to correspond to the videos in the course. The naming convention is CHAPTER#_MOVIE#. As an example, the branch named 02_03 corresponds to the second chapter and the third video in that chapter. Some branches will have a beginning and an end state. These are marked with the letters b for "beginning" and e for "end". The b branch contains the code as it is at the beginning of the movie. The e branch contains the code as it is at the end of the movie. The main branch holds the final state of the code when in the course.

When switching from one exercise files branch to the next after making changes to the files, you may get a message like this:

error: Your local changes to the following files would be overwritten by checkout:        [files]
Please commit your changes or stash them before you switch branches.
Aborting

To resolve this issue:

Add changes to git using this command: git add .
Commit changes using this command: git commit -m "some message"
