What will I learn?
Master key data structures in Java by creating a high-speed in-memory storage system from the ground up. Learn to represent products and orders, create neat APIs, apply HashMap for indexing, and select the best collections for quick searches and records. Practise handling multiple threads with atomic counters, locks, and safe updates, then check your results using benchmarks, performance checks, and thorough unit and integration tests in this practical, focused course.
