Mastering Java Singleton: From Lazy Initialization to Enum with Thread‑Safety

This article walks through multiple Java Singleton implementations—lazy initialization, double‑checked locking, volatile‑protected, static‑inner‑class, and enum—explaining their thread‑safety characteristics, the pitfalls of instruction reordering, and how reflection and serialization can break or preserve the pattern.

Why volatile Is Not Thread‑Safe: A Java Increment Test

The article presents a Java program where 100 threads each increment a volatile int 1,000 times, showing that the final value may be less than the expected 100,000, and explains that volatile only guarantees visibility, not atomicity, making it unsuitable for concurrent modifications.
