| Java streams performance and optimization | JCON EUROPE 2026 | 2026-04-20 |
Streams often run substantially slower than equivalent loops when misused: 3x performance loss appears in examples where textbook functional patterns and… | ||
| When Greed Is Good: Understanding Java Stream Performance | JCON EUROPE 2026 | 2026-04-20 |
Explains how Java streams actually execute by showing JMH benchmarks, JITWatch assembly, and flame graphs that reveal surprising costs: adding a limit produces… | ||
| Java and WebAssembly | JavaOne 2026 | 2026-03-17 |
Demonstrations show zero‑install Java running in the browser: a full SnapCode IDE and playgrounds compile and run client‑side with a ~15 MB runtime and ~1 s… | ||
| Streams – Below the Surface | Voxxed Days CERN 2026 | 2026-02-10 |
Explains how Java Streams build a pipeline from spliterator through intermediate ops to a terminal op, why Gatherers (Java 23) let you write custom… | ||
| The Java Class File API | Jfokus 2026 | 2026-02-02 |
Many third party libraries like ASM BCEL and Javassist exist but Java 24 now provides a standard Class File API since Java 24 that parses and builds class… | ||
| Project Valhalla: Flat Value Types in Java | JCON EUROPE 2025 | 2025-05-12 |
Project Valhalla adds a new value modifier so small data classes flatten like primitives, removing per-instance heap headers; a 100M-point Brownian demo shows… | ||
| Virtual Threads, Structured Concurrency, Extent Locals: When to Use Them & How | JCON EUROPE 2025 | 2025-05-12 |
Virtual threads run on platform carrier threads so blocking calls become cheap and throughput jumps — a 1,000-sleep request demo finishes in ~1s on virtual… | ||
| Java for Small Coding Tasks | JavaOne 2025 | 2025-03-18 |
Argues Java is practical for small scripts by showing concrete tooling and demos: the Java launcher compiles in memory so no class files, unnamed classes let… | ||
