Effective Java SE 11-21 APIs/Lang Features Makes Your Life Easier.
summary
Covers concrete Java SE 11–21 changes and how to use them: run a one‑file program with single-file source launch so no separate javac step, replace small curl scripts with the built-in HTTP Client (sync/async, WebSocket), use var for lambda params, switch expressions with yield, text blocks, records + pattern matching, foreign‑memory and linker APIs (off‑heap IO), sequence collections, default UTF‑8, jwebserver and packaging to produce MSI/EXE, and Java 21 ships virtual threads production-ready and structured concurrency for lightweight concurrency.
