Course Kotlin Programming

In the course Kotlin Programming participants learn to use the object oriented and functional language Kotlin for software development. Kotlin is a modern statically typed language that is fully compatible with Java and runs on the Java Virtual Machine (JVM). Kotlin has modern language features such as type inferences, null safety, coroutines and unchecked exception which are lacking in Java. Moreover Kotlin code is much more compact compared to Java.

    Kotlin Intro

    The course Kotlin Programming starts with an overview of a number of important features of Kotlin. Attention is paid to the syntax simplifications in the Kotlin language compared to Java. It is also discussed that Kotlin code can be compiled not only to Java, but also to JavaScript or native code.

    Language Syntax

    Next the language syntax is covered with type inference, mutable and immutable variable declarations, if and when expressions, ranges, loops and iterators.

    Classes and Objects

    With regard to object oriented programming, class initialization, primary and secondary constructors final and open classes, abstract classes and interfaces are treated. And also attention is paid to data classes in which methods such as equals, toString and hashCode are automatically generated.


    Kotlin also supports functional programming and part of the program of the course are lambda functions, higher order function, passing functions as parameters and returning functions. Also to extension methods, destructuring declarations, nested functions and extracting parameters with the spread operator are discussed.

    Collections and Generics

    Also covered is the Collection Framework in Kotlin that supports mutable and immutable collections and sequences with lazy evaluation. Parameterized types with generics are also covered. And delegation in Kotlin with lazy and observable properties is explained.


    Finally attention is paid to the use of coroutines in Kotlin which can be considered as lightweight threads and which are excellent for asynchronous handling.
