Kotlin Essential Training (2018)

- [David] My name is David Gassner. Welcome to this beginning course about programming with Kotlin, a newer programming language developed by tools maker JetBrains. This course focuses on the version of Kotlin that runs on the Java virtual machine. I'll first show how to set up and configure the software you'll need to develop with Kotlin and I'll show you how to create your first Hello World application in IntelliJ IDEA. I'll then describe the language's fundamental building blocks, including how Kotlin code compiles to Java Bytcode and how to declare and use variable values.

I'll demonstrate working with simple values and complex objects such as data collections, and I'll show you how to manage programming flow with conditional statements and loops, and then I'll explore a variety of ways to create reusable code in Kotlin with functions, classes, interfaces, enumerations, and more. Whether you're creating Android apps or working in another environment that supports Kotlin, I hope this course helps you get started with this great new language.
