Deze cursus verschaft u een grondige kennis van de kern functies van de Java programmeer taal en de Application Programming Interfaces (API) die gebruikt worden bij het bouwen van object-oriented applicaties met het Java Standard Edition platform.
Deze cursus leert u praktische vaardigheden bij het:

• Bouwen van Java applicaties met de nieuwste JDK Technieken
• Ontwikkelen van uw object-oriented vaardigheden
• Identificeren van "best practices" van de Java taal om robuuste Java-applicaties te maken
• Toepassen van Lambda expressions in Java applicaties
• Opslaan en manipuleren van data met collections
• Omgaan met files, directories en file systems
• Verbinden met databases met standaard SQL queries via JDBC
• Creëren van high-performance multi-threaded applicaties
• Bouwen van grafische toepassingen met SWING.

U kunt deze cursus gebruiken om uw Java programmeer vaardigheden verder te ontwikkelen, en als voorbereiding voor het examen: Oracle Certified Professional, Java SE 8 Programmer (1Z0-809).
