Ist Java 11 kostenlos?
Verschärfend kommen wichtige Änderungen hinzu, die den Einsatz des Oracle JDK beziehungsweise des Oracle JRE in Produktion betreffen: Ab Java 11 sind beide nur noch in Entwicklungs- und Testumgebungen kostenfrei nutzbar. Alternativ stellt Oracle JRE und JDK über das OpenJDK weiterhin kostenlos bereit.

How does a Java developer use a JDK?
