What will I learn?
Master core data structures and algorithms in Java with a focused, hands-on course that goes beyond theory. You will design hash-based maps, implement efficient top-k queries, and build time-windowed action logs while learning complexity analysis, memory behavior, and concurrency basics. Practice microbenchmarking, profiling, and unit testing, and finish with clean documentation and reusable, production-ready code.

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