Gehen Sie über einfache Tutorials hinaus und schaffen Sie eine echte Grundlage in der professionellen Softwareentwicklung mit Java 21. Dieses Buch ist ein umfassender Praxiskurs, der Sie von Ihrer allerersten Codezeile bis zur Erstellung einer vollständigen, getesteten und persistenten Kommandozeilenanwendung begleitet. Es ist der definitive Ausgangspunkt für angehende Entwickler, Studenten oder Fachleute, die eine der beständigsten Programmiersprachen der Welt meistern möchten.
Klar und praxisorientiert geschrieben, baut dieser Leitfaden Ihr Wissen systematisch von Grund auf auf. Sie lernen nicht nur die Syntax, sondern verstehen auch das Warum hinter den Kernprinzipien des Softwaredesigns. Der gesamte Weg ist so strukturiert, dass Sie jedes Konzept verstehen, bevor Sie zum nächsten übergehen. Den Abschluss bildet ein finales Projekt, in dem Sie alle erlernten Fähigkeiten anwenden werden.
Im Inneren finden Sie:
Eine solide Grundlage: Beginnen Sie mit den absoluten Grundlagen von Java, von der Einrichtung Ihrer Umgebung bis zur Beherrschung von Variablen, Kontrollstrukturen und Methoden.
Echtes objektorientiertes Denken: Entwickeln Sie ein tiefes Verständnis für Klassen, Objekte und die vier Säulen der OOP. Lernen Sie nicht nur, was sie sind, sondern wie man wie ein objektorientierter Designer denkt.
Moderne Java-21-Funktionen: Bringen Sie sich auf den neuesten Stand, einschlie lich Lambda-Ausdrücken, der Stream-API und dem revolutionären neuen Nebenläufigkeitsmodell mit virtuellen Threads und strukturierter Nebenläufigkeit.
Praxisnahe Fertigkeiten: Lernen Sie das Handwerkszeug. Gehen Sie über die Sprache hinaus und verwalten Sie Ihre Projekte mit Maven, schreiben Sie professionelle Unit-Tests mit JUnit, handhaben Sie Datei-E/A und stellen Sie eine Verbindung zu einer Datenbank mit JDBC her.
Ein vollständiges Abschlussprojekt: Festigen Sie Ihr Wissen, indem Sie eine Buchkatalog-Anwendung von Anfang bis Ende erstellen und dabei Prinzipien des sauberen Designs, der Datenpersistenz und des automatisierten Testens anwenden.
Ob Ihr Ziel darin besteht, eine neue Karriere zu starten, Ihre vorhandenen Fähigkeiten zu verbessern oder Ihre eigene Software zu entwickeln, Entwickeln mit Java 21 bietet den direkten und gründlichen Weg, um sauberen, modernen und effektiven Code zu schreiben.
