Sample Code
This page describes code samples that might be useful, either when learning Kotlin or figuring out a technique for your application.

Course Repositories
We maintain public repositories in GitLab. The following projects are available:
- demos/*: full applications (console and desktop), with issue lists, documentation etc.
- kotlin-language: Kotlin language examples. Used in lectures.
- sample code: smaller, limited applications used to demonstrate specific functionality e.g., database connections, UI dialogs. Grouped into desktop/android folders based on platform.
- templates: project documents e.g., meeting minute templates.
To get a copy, git clone the URL for the repository that you want to open. This command, for instance, would create a copy of the kotlin-language project in a directory of the same name.
$ git clone https://git.uwaterloo.ca/cs346/kotlin-language.gitThe sample code folder contains code to accompany the lecture slides.
