Kotlin is a concise new programming language that’s used for Android development and in other Java-based environments. Among its many benefits, Kotlin is 100% compatible with Java and is fully supported by Google. This course provides a comprehensive overview of the most essential features of Kotlin, specifically the version that runs on the Java Virtual Machine (JVM). Instructor takes you from project setup, through rudimentary syntax, to working with variables and creating custom classes. He shows how to manage program flow with functions, loops, conditional statements, and try/catch exception handling. He also shows how to manage data in memory with fixed-size arrays and dynamic data collections: lists, sets, and maps. Finally, he describes how to implement inheritance-a key feature of reusable, object-oriented code-with classes, interfaces, anonymous objects, and anonymous functions (aka lambda expressions).
