Build Spring Boot Apps with the Kotlin Programming Language

سرفصل های دوره

Kotlin is an exciting programming language that's concise, has immutable variables, and almost always gets rid of null pointer exceptions. If you're a Java developer looking to get started with Kotlin, then this course is for you. Join instructor Matt Greencroft as he demonstrates how to build high-quality Spring Boot applications with Kotlin, specifically the version of Kotlin that runs on the Java Virtual Machine (JVM). As Matt covers a range of key concepts—from classes to loops—he explains how each Kotlin feature compares to the equivalent one in Java.
