Visualiser l'API de concurrence Java
summary
A JavaFX thread visualizer runs compiled classes by reflection and paints activity across a fixed 360‑slot array while computeIndex deliberately burns CPU to show timing differences, interrupts and policies. Examples use raw Threads, ExecutorService types (single, fixed, cached, virtual threads) and a fork‑join pool that steals work across 2, 4, 8 or 16 workers. A race on a counter that runs 100 million increments per task across eight tasks produces ~117M instead of 800M until switched to AtomicLong, proving fixes and demonstrating shutdown/interrupt forwarding.
