Dieser Anhang bietet Ihnen eine detaillierte Inhaltsangabe des Application Programming Interface (API) von Java. Das Java API ist eine Sammlung von Klassen, die von Java-Entwicklern entwickelt worden sind. Es soll Ihnen bei der Entwicklung Ihrer eigenen Klassen, Applets und Anwendungen helfen.
Die Klassen des Java API sind in Pakete gruppiert, von denen jedes verschiedene Klassen und Schnittstellen haben kann. Darüber hinaus können die Items verschiedene Eigenschaften wie Felder und/oder Methoden haben.
Es ist möglich, in Java zu programmieren, ohne viel über das API zu wissen. Jede Klasse, die Sie entwickeln, wird aber zumindest von einer Klasse innerhalb des API abhängen. Wenn Sie komplexere Programme entwickeln, in denen sich Zeichenketten, Sockets und graphische Schnittstellen befinden, ist es sehr hilfreich, wenn Sie die Ihnen von Sun zur Verfügung gestellten Objekte und die Eigenschaften dieser Objekte kennen.
Der folgende Anhang listet die Objekte auf, die im Java API definiert sind, zusammen mit ihren Oberklassen, Schnittstellen, Methoden und Feldern – sofern anwendbar. Dabei sind aber einige Details zu bedenken:
Denken Sie abschließend daran, daß diese Information (genauso wie Erklärungen jeden Feldes und jeder Methode) auch in zusammengefaßter Form unter http://www.javasoft.com/JDK-1.0/api/packages.html vorhanden sind. Sie können sich unter http://www.javasoft.com/ auch den Java-Quell-Code selbt herunterladen.
Obwohl es das kleinste ist, ist dieses Paket als ein Ergebnis der Applet-Klasse am bemerkswertesten. Es ist voll von nützlichen Methoden. Die Applet-Klasse legt das Fundament für alle Applets und kann Ihnen die Informationen geben, die die Umgebung des Applets über die AppletContext Schnittstelle betreffen.

Das Java Abstract Window Toolkit (AWT) besteht aus Quellen, mit denen Sie interessante, attraktive und nützliche Schnittstellen für Ihre Applets erstellen können. Das AWT enthält nicht nur Verwaltungsklassen wie GridBagLayout, sondern auch einige konkrete interaktive Tools wie Button und TextField. Was aber viel wichtiger ist, ist die Tatsache, daß Sie mit der Graphics-Klasse über ungeahnte graphische Möglichkeiten verfügen. Sie haben damit die Möglichkeit, Formen zu erzeugen und Bilder anzuzeigen.

java.awt.image ist sehr eng mit dem java.awt-Paket verbunden, Dieses Paket enthält Tools, mit denen Sie Bilder, die über das Netzwerk kommen, behandeln und manipulieren können. Da alle Klassen und Schnittstellen in diesem Paket eng miteinander verbunden sind, werden Sie sehen, daß viele Methoden mehrere Male erscheinen.

Das java.io-Paket dient als Standard Input/Output-Bibliothek für Java. Mit diesem Paket können Sie Datenströme auf verschiedene Weise erstellen und bearbeiten. Sie können damit auch Datentypen, die so einfach wie String und so komplex wie StreamTokenizer sind, verwenden. Es ist aber auch sinnvoll, den Code genauer zu studieren, da dieses Paket sehr von dem basic InputStream- und OutputStream-Klassen und von Schnittstellen abhängt.

Diese Klassen sind das »Herz« von Java. Hier bekommen Sie nicht nur die Grunddatentypen wie Integer und String, sondern auch Mittel für die Fehlerbehandlung durch die Throwable- und Error-Klassen. Darüber hinaus versorgen Sie der SecurityManager und System-Klassen mit einigen Steuerungsmöglichkeiten für das Java Laufzeit-System.

Das sun.tools.debug-Paket ist für remote Debugging mit dem Java Debugger (JDB) geeignet. Wenn Sie diese Klassen untersuchen, werden Sie den Prozeß verstehen lernen. Für die Erstellung von normalem Code wird dieses Paket nicht benötigt. Mit diesem Paket bekommen Sie das Fundament, um einen nützlicheren und anwenderfreundlicheren Debugger zu entwicklen – etwas, das von Sun offen gefördert wird.

LocalVariable
Die sun.tools.debug.LocalVariable-Klasse ist keine public-Klasse, aber ziemlich beschränkt auf den Gebrauch innerhalb des sun.tools.debug-Pakets. Das liegt an der Tatsache, daß die Klasse selbst und alle ihre Felder als »friendly« (es wurden also keine Zugangsmodifizierer angegeben) definiert werden. Obwohl es nicht für den Gebrauch von Java-Entwicklern gedacht ist, ist hier denoch aufgeführt, da diese Klasse von anderen Klassen in diesem Paket abhängt.

Ausnahmen geben Ihnen ein Mittel an die Hand, mit dem Sie gewöhnliche Laufzeitprobleme, die bei der Ausführung Ihres Programmes auftreten, handhaben können. Ausnahmen werden von Methoden aufgeworfen und mit try-catch-Blöcken gehandhabt.
Alle Ausnahmen stammen von java.lang ab und bestehen nur aus zwei Konstruktionsmethoden. Deshalb werden hier nur die Konstruktionsmethoden für java.lang.Exception aufgelistet. Wenn nicht anders notiert, werden alle Ausnahmen ohne Parameter oder mit einer beschreibenden Zeichenkette als Parameter erstellt.

Während Fehler und Ausnahmen beide auf der java.lang.Throwable-Klasse basieren, können Sie mit Errors kritischere Laufzeitfehler behandeln. Fehler können genauso wie Ausnahmen behandelt werden, aber wenn Sie das Problem nicht genau verstehen oder eine geeignete Art zur Lösung gefunden haben, sollten Sie keine Fehlerbehandlung in Ihren Code mit aufnehmen.
Ähnlich wie Ausnahmen stammen alle Fehler von java.lang.Errors ab. Die meisten Fehler enthalten nur eine einzige Konstruktionsmethode und meistens auch nur ErrorName( ) und ErrorName(String message). Es sind alle Fehler aufgelistet, die mit den hier genannten Konstruktionsprinzipien nicht übereinstimmen.
