What will I learn?
Master modern data processing with this concise Java Streams Course. Learn core stream creation, filtering, mapping, and reduction, then move into advanced collectors for grouping, partitioning, and summarising. Practice sorting, pagination, and complex queries, refactor legacy loops into clean pipelines, and understand collections and immutability. Finish with testing, debugging, profiling, and parallel stream performance tuning for reliable, efficient code.
