on YouTube ↗50m

" summary

Java road map focuses on four concrete changes and their current status: string templates with template processors (JEP 430 proposal) can produce parsed SQL or JSON objects instead of raw concatenated strings; the Vector API targets CPU SIMD (512‑bit registers) for 10–16x hot loops while the Foreign Function and Memory APIs are in JDK 19 preview using jextract; Valhalla introduces value and primitive classes plus universal and specialized generics to eliminate boxing and improve cache layout; virtual threads and structured concurrency are previewed in JDK 19 as low‑memory, carrier‑thread multiplexed threads.
