The Best of Java Shorts Shorts Show: 100 Snippets in 45 Minutes
summary
Collection of concrete, runnable recipes that demonstrate actual outcomes: 100 snippets that use only javac and VS Code, show Java 21 on Corretto, and include examples that surprise — e.g., run Java as a shell script, built a tiny clipboard washer that strips styling (works but Swing blocks Graal native image), a JWT decoder, file watch and file diff, timers and ScheduledThreadPool, emoji and colored terminal output, and producing a minimal JVM via jlink subset jddvm that boots and runs. Everything uses core Java, no external deps.
