What will I learn?
Master key data structures and algorithms in Java through a practical, hands-on course that goes beyond just theory. You will create hash-based maps, develop efficient top-k queries, and construct time-windowed action logs, all while studying complexity analysis, memory usage, and basic concurrency. Gain skills in microbenchmarking, profiling, and unit testing, ending with well-documented, reusable code ready for production.

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...
