Functional Libraries for Java 8 and 9
summary
Demonstrates concrete libraries and live code: jOOL replaces collect+grouping and shows jOOL window functions that produce running balances from tuples; Vavr supplies Vavr immutable collections with lifting and memoization to avoid exceptions; JUnit 5 creates dynamic tests generated for n=1..30; RxJava composes timed observables; Vert.x serves a simple Vert.x HTTP server route that returns JSON — each example compiles and runs in the demo.
