In this issue, we examine three leading frameworks for microservices: Javalin, which is a very lightweight, unopinionated Kotlin-based web framework; Micronaut, which handles all feature injection at compile time and so loads extremely fast; and Helidon, which is a cloud native framework that generates a pure Java SE JAR ile that can be run as a service or a complete app. Java programs can have two kinds of comments: implementation comments and documentation comments. Implementation comments are those found in C++, which are delimited by /**/, and //. Documentation comments (known as "doc comments") are Java-only, and are delimited by /***/.
