Opleiding: Kotlin Fundamentals

Wil je leren programmeren in een krachtige, moderne taal die geschikt is voor front-end, back-end en mobiele platforms? Kies dan Kotlin: one language to rule them all.

Beschrijving

Ontwikkelaars met ervaring in programmeren leren Kotlin, een moderne programmeertaal. Het maakt niet uit welke voorkennis je precies hebt, zolang je de principes van (objectgeoriënteerd of functioneel) programmeren kent.

Je leert de fundamentele eigenschappen van Kotlin, waarna je direct aan de slag gaat met het schrijven van Kotlin-code. Aan de hand van codevoorbeelden leer je de concepten. Aansluitend kun je de training "Advanced Kotlin" volgen, die meteen hierna start.

Leerdoelen

• Explain the most important characteristics of Kotlin, and why it was created. [Understand]
• Produce a stand-alone Kotlin program that uses a main function, other top-level functions, top-level properties and type inference. [Apply]
• Produce code that declares and uses extension functions and properties. [Apply]
• Use vararg, infix and destructuring. [Apply]
• Construct a Kotlin application that uses classes (including data, abstract, inner and nested classes), properties, interfaces, sealed classes and a when statement. [Apply]
• Explore the purpose of objects, lamdbas and scope functions like with, let and apply by implementing the Singleton design pattern using these constructs. [Apply]
• Characterize the difference between a sequence and a collection, and how the methods in the functional APIs behave for both sequences and collections. [Understand]
• Explain how primitives and other basic types like Strings work (including text blocks and String templates), above and under the hood, including types like Any, Unit and Nothing. [Understand]
• Construct code using nullability in the best way, along with the necessary operators. [Apply]
