What will I learn?
Master main data structures in Java by creating a fast in-memory store from the ground up. Learn to represent products and orders, create simple APIs, use HashMap for indexes, and pick the best collections for quick searches and records. Practice handling multiple threads with atomic counters, locks, and safe updates, then check your work with benchmarks, profiling, and good unit and integration tests in this short, practical course.
