This is a demo of very basic kotin stuff
Kotlin is a language created by Jetbrains (intellij geeks). A few years ago as it really grew in popularity, a new group called the Kotlin Foundation was created to manage the language. A bit after Google announced that kotlin was officially a supported first class language for Android development. Spring announced around the same time that they added explicit support for kotlin in spring boot 2 and spring 5 for functional programming (and included amongst other things a new Kotlin DSL for it's endpoints). Kotlin is released under the Apache 2 license

This was a design goal from the start. This makes it very easy to start mixing kotlin and java, simply add the dependency to gradle/maven. A very common starting point for adding Kotlin to a project is replacing DTOs and Pojos, making them actually readable (getter/setter/toString/equals/hashcode/copy are autogenerated, I will show this in a bit)
