Each company has large software systems that have been continuously developed over many years, and the maintenance of these systems is becoming tougher and more expensive year after year. Against the background of new architectural paradigms such as microservices, these systems should now be modern, scalable and flexible. There is hope though - you can get rid of these big, cumbersome monoliths by decomposing them down into smaller microservices.

Yes, you read it correctly, there are alternatives. Although the top dog Spring is enjoying great popularity with Java applications, we should not forget that there are also other frameworks worth taking a look at. Here we’ll be talking about Micronaut, a relatively new framework, but one that offers some interesting features that make it a real rival to Spring, especially in the cloud environment. In this article, we will implement an application using Spring Boot and then using Micronaut. Then, we will compare the two approaches and see where each framework is superior to the other.
The switch case expressions in Java go back pretty much to the beginnings of the programming language. It was basically a compromise in language design to make it easier for C++ developers to switch to Java. Relics like break and fall-through were not very intuitive and caused a lot of errors. In addition, the case statement was very limited regarding the notation of the values. Fortunately, this all changes with Java 12. The syntax has been slightly modified to allow specifying one expression and multiple values. In this way, case differences can be formulated much more elegantly.
