Kotlin: from Zero to Ninja


Kotlin is now the most used language on the JVM after Java. It's also very much loved, and for good reasons: pragmatic, simple, less verbose than Java, but not too concise either, completely compatible with Java, well integrated in popular frameworks like Spring Boot and others. It's also the official language of the Android platform. In this training, you will learn the essentials of the language, by practicing on small exercises, with the help of your teacher or course, but also of automated tests.

Goals

  • Master the syntax of the language.
  • Understand and use the design principles of the language.
  • Interoperate with Java code.
  • Be familiar with the essentials of the Kotlin standard library.

Public

This training is for developers who want to discover the Kotlin language, but already are familiar with Java.

Prerequisite

Knowledge of the basics of Java, OO and functional programming. A doubt on your current knowledge level? Send us an email!

Modalities

The training can be followed in person or remotely, during public sessions that we organize regularly, or during a session dedicated to your team. You can register for a session up until the starting date, in the limit of available seats (usually 6 or 7). We may have to re-schedule a session if we don't have at least 3 persons registered, up until 2 weeks before the starting date. Do not hesitate to contact us to define your needs, and check if the training is the right one for you.

Evaluation

The automated tests allow checking if your code is correct. The trainer will of course answer the questions and have a look at the written code to spot things that can be improved.

Requirements

Each trainee must have his/her own computer to be able to do the exercises (the OS can be whatever you prefer), and an Internet connection. For an in-house training, the trainer will also need a video-projector, an Internet connection, and a whiteboard or paperboard.
