Java, Life is Short!
summary
Shows concrete tools and demos: uses SDKMAN to switch JVMs, spins up a Quarkus project with Quarkus Dev hot reload and continuous testing, and adds testcontainers provisioning Postgres to run a real DB in ~30s. Builds a container image (JVM or GraalVM native) with quarkus image build, deploys to Kubernetes from generated YAML, and a native binary starts in ~171 ms. Also demos jbang running a GPT-backed code generator that returns a working square‑root CLI.
