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.
