What will I learn?

Master core data structures in Java by building a high-performance in-memory store from scratch. Learn to model products and orders, design clean APIs, use HashMap-based indexes, and choose optimal collections for lookups and history. Practice concurrency with atomic counters, locks, and transactional updates, then validate your work with benchmarks, profiling, and solid unit and integration tests in a compact, hands-on course.
