3Neues und Änderungen in JDK 9
In diesem Kapitel schauen wir uns relevante Erweiterungen aus Java 9 an, beispielsweise das Process-API. Außerdem betrachten wir die Ergänzungen im Stream-API sowie in java.util.Optional<T>, aber auch die Collection-Factory-Methoden. Darüber hinaus findet man Ergänzungen in der Klasse java.io.InputStream sowie diverse Neuerungen, unter anderem im Bereich Concurrency: Zum einen bietet die Klasse java.util.concurrent.CompletableFuture<T> mehr Funktionalität.
