Kotlin

Kotlin's versatility, modern features, and seamless integration with existing Java code have contributed to its adoption in a wide range of application development scenarios, making it an attractive language for both new and experienced developers.

Day 1 kicks off with an orientation session where participants will be introduced to each other, receive an overview of the course structure, and discover the advantages of using Kotlin. The day continues with a deep dive into Kotlin's foundational concepts, including variables, data types, arrays, and the basics of functions. Participants will also explore Kotlin's commitment to null safety and its concise handling of operators, conditional expressions, loops, and ranges. The day wraps up with a look at Kotlin's approach to functions, covering their parameters, infix notation, local and generic functions.

Day 2 shifts focus to object-oriented programming with Kotlin. Attendees will learn about Kotlin's streamlined handling of classes, including properties, constructors, and member functions. The day covers inheritance and visibility modifiers, as well as more advanced features like delegation, interfaces, abstract classes, and extension functions. Special attention is given to Kotlin-specific constructs such as data classes, enum classes, parameterized classes, inline classes, and the use of anonymous objects. The day concludes with an overview of Kotlin's powerful collection framework, demonstrating how to work with lists, sets, maps, and perform various collection operations.

Day 3 takes participants beyond the basics to explore more sophisticated features of Kotlin. The day begins with exception handling and annotations, followed by an understanding of type aliases and the benefits of sealed classes and interfaces. Attendees will then delve into destructuring, lambdas, and the range of scope functions, as well as advanced function types, including inline, tail recursive, and higher-order functions. The course concludes with a look at reflection, the power of coroutines for asynchronous programming, and the nuances of Java interoperability, ensuring that participants are well-equipped to integrate Kotlin into their existing Java projects.

By the end of this course, attendees will have gained a thorough understanding of Kotlin's capabilities and how to apply them to create clean, efficient, and robust applications.

This course is taught in Romanian, with course materials available in either English, or Romanian. The course can be customized - on request.
