Discovering the Power of Type-Safe Java Development Start from a familiar legacy snippet: List inventory = new ArrayList();. It compiles, ships, and eventually bites back with ClassCastException. The fix is not a one‑off cast; it’s a mindset: design APIs that express intent through types and let the compiler enforce correctness. Generics have been in Java for years, but deep fluency—wildcards, vari...

Discovering JFR: A Journey into Modern Java Profiling Excellence Symptom: memory usage drifts under real production load. Constraint: profiling cannot degrade latency or throughput. Solution: Java Flight Recorder (JFR) — the built‑in, low‑overhead recorder that captures CPU, memory, GC, I/O, and custom events from live systems with typically under 2% impact. With JFR, production evidence replaces g...
