Ein wichtiger Bestandteil vieler Anwendungen ist die Verarbeitung von Informationen aus Dateien, die das dauerhafte Speichern von Daten ermöglichen. Java bietet zur Ein- und Ausgabe in den Packages java.io und java.nio einen objektorientierten Zugang und mehrere Möglichkeiten zum Erstellen, Lesen, Aktualisieren und Löschen von Dateien. Dazu existiert die Klasse java.io.File seit Javas Anfangstagen. Zwischenzeitlich kam mit dem Interface java.nio.file.Path eine leichter nutzbare Variante zur Interaktion mit dem Dateisystem hinzu. Ebenso wurden einige grundlegende Funktionalitäten in die Utility-Klasse java.nio.file.Files integriert. Nachfolgend betrachten wir die neueren und einfacher handhabbaren Varianten.
