2. Using Java 8IntStream Using core Java, we could generate indexes usingIntStreamand then use them to extract corresponding elements from two collections: IntStream .range(0, Math.min(names.size(), ages.size())) .mapToObj(i -> names.get(i) +":"+ ages.get(i))// ... 3. Using...

Based on the proposed framework, a reduction library (RedLib) has been developed for Java with direct support for many common reduction operations on collections and maps. Furthermore, the paper studies the usage of the framework for common and complex cases and evaluates its performance, based ...
