What Java Developers Can Learn From ZIO
summary
ZIO gives Java-like projects concrete tools: open up to four files in parallel with forEachParN, abort on the first parse error while bracket guarantees each file handle closes and running tasks are interrupted, implement actor-transfer atomically using STM with optimistic retries and composable locks, and spawn nonblocking workflows as fibers + promises (example: fork a 5s delay then complete a promise). ZIO describes workflows (under 20 primitives) and runs them via its interpreter runtime so interruption, finalizers and composition work reliably.
