What Will I Learn?
This short, practical Singleton in Java course shows you exactly how to design safe, efficient singletons for real applications. You will compare key implementation patterns, understand threading and the Java memory model, and integrate configuration and logging singletons cleanly. Learn to avoid common pitfalls, improve testability, and choose the right approach for performance, reliability, and maintainable code.

Develop Skills
- Implement Java singletons: master eager, lazy, enum, and holder patterns fast.
- Design thread-safe singletons: apply volatile, locks, and safe publication correctly.
- Build robust config and logging singletons: clean APIs, lazy load, safe shutdown.
- Avoid singleton anti-patterns: improve testability, decouple services, cut risks.
- Diagnose singleton issues: spot leaks, contention, and security holes in Java apps.

Your classes are perfect. I purchased the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... thank you for everything you do, I've already recommended you to others...
