# Aufgabenblatt 8
|
||||
|
||||
## Allgemeine Anmerkungen
|
||||
Ihre Lösung für dieses Aufgabenblatt ist bis Dienstag, 13.6., 11h durch `git commit` und `git push`
|
||||
abzugeben.
|
||||
Wenn Sie zusätzlich zu den gefragten Klassen und Interfaces weitere Klassen oder
|
||||
Interfaces definieren, achten Sie darauf, dass die Klassennamen mit `My` beginnen, um Konflikte
|
||||
mit späteren Aufgabenblättern zu vermeiden.
|
||||
|
||||
Weiters werden die Dateien `StateFileNotFoundException.java`,
|
||||
`StateFileFormatException.java`, `ReadDataUtil.java`, `Simulation8.java`, `Simulation9.java`,
|
||||
`Aufgabe8Test.java` und das Verzeichnis `states` mit `txt`-Dateien mitgeliefert.
|
||||
|
||||
## Ziel
|
||||
Ziel der Aufgabe ist das Verständnis und die Anwendung der Konzepte: Java-Collections, Eingabe mit
|
||||
Validierung, Exceptions (S. 110-123).
|
||||
|
||||
## Beschreibung der gegebenen Dateien
|
||||
|
||||
- [states](../states) ist ein Verzeichnis, in dem mehrere Dateien mit der Endung `.txt`
|
||||
mitgeliefert werden. Diese enthalten Daten von je einem Himmelskörper sowie dessen Positionen und
|
||||
Geschwindigkeitsvektoren für alle Tage der Jahre 2019-2021. Die Angaben sind wie gewohnt in
|
||||
kartesischen Koordinaten, wobei die Sonne den Urspung des Koordinatensystems bildet und die
|
||||
Ekliptik die x-y-Ebene darstellt. Die Daten stammen von [https://ssd.jpl.nasa.gov/horizons.cgi#top](https://ssd.jpl.nasa.gov/horizons.cgi#top).
|
||||
|
||||
**ACHTUNG**: Die Werte sind in km bzw. km/sec angegeben!
|
||||
|
||||
- [StateFileNotFoundException](../src/StateFileNotFoundException.java) enthält die Definition
|
||||
der Klasse `StateFileNotFoundException`. Diese sollen Sie vervollständigen.
|
||||
- [StateFileFormatException](../src/StateFileFormatException.java) enthält die Definition
|
||||
der Klasse `StateFileFormatException`. Diese sollen Sie vervollständigen.
|
||||
- [ReadDataUtil](../src/ReadDataUtil.java) ist eine Klasse mit einer statischen Methode zum
|
||||
Einlesen von Position- und Bewegungsvektoren von Himmelskörpern aus Dateien.
|
||||
Diese sollen Sie vervollständigen.
|
||||
- [Simulation8](../src/Simulation8.java) ist ein Gerüst für eine ausführbare Klasse. Hier soll
|
||||
die Simulation analog zur Klasse `Simulation` implementiert werden (damit Sie Ihre [ursprüngliche
|
||||
Datei](../src/Simulation.java) nicht überschreiben müssen).
|
||||
- [Simulation9](../src/Simulation9.java) ist eine leere Datei. Hier soll eine weitere Simulation
|
||||
implementiert werden, die so wie `Simulation8` funktioniert, mit dem Unterschied, dass anstelle
|
||||
der selbst implementierten Datenstrukturen nur vorgefertigte Klassen aus dem
|
||||
Java-Collection-Framework benutzt werden sollen.
|
||||
- [Aufgabe8Test](../src/Aufgabe8Test.java) ist eine vorgegebene Klasse, die Sie zum Testen Ihrer
|
||||
Implementierung verwenden sollten. Bei einer fehlerfreien Implementierung sollten bei der
|
||||
Ausführung dieser Klasse keine Exceptions geworfen werden und alle Tests als erfolgreich ("successful")
|
||||
ausgegeben werden. Entfernen Sie die Kommentarzeichen, um diese Klasse verwenden zu können. Sie
|
||||
müssen diese Klasse nicht weiter verändern, können aber eigene Testfälle hinzufügen.
|
||||
|
||||
|
||||
## Aufgaben
|
||||
|
||||
1. Ändern Sie Ihre Implementierung, sodass ein `MassiveIterator` eine Exception
|
||||
vom Typ `java.util.NoSuchElementException` wirft, falls `next()` aufgerufen wird,
|
||||
jedoch der Iterator keine weitere Iteration hat (`hasNext()` liefert `false`).
|
||||
|
||||
2. Ändern Sie den Iterator von der von `getKeys()` zurückgelieferten
|
||||
Sichtweise auf `MassiveForceTreeMap` so, dass `remove()` überschrieben wird
|
||||
([siehe API Dokumentation](https://docs.oracle.com/javase/8/docs/api/java/util/Iterator.html#remove--)),
|
||||
sodass der Iterator Einträge in Objekten von `MassiveForceTreeMap` löschen kann. Achten Sie
|
||||
darauf, dass hier in bestimmten Fällen eine `java.lang.IllegalStateException` geworfen werden
|
||||
soll. Der Iterator von `HierarchicalSystem` muss nicht geändert werden.
|
||||
|
||||
3. Validierung von Eingabedaten:
|
||||
- Implementieren Sie in der Klasse `ReadDataUtil.java` die Methode `readConfiguration`.
|
||||
Es soll ein gepufferter Stream zum Einlesen genutzt werden (siehe Skriptum Seite 128).
|
||||
Erstellen Sie zum Testen auch Varianten der txt-Dateien mit Formatfehlern.
|
||||
- Fügen Sie der Klasse `NamedBody` bei Bedarf
|
||||
eine Methode `setState(Vector3 position, Vector3 velocity)` zum Setzen der Position
|
||||
und des Geschwindigkeitsvektors des Himmelskörpers hinzu.
|
||||
- Definieren Sie die beiden angegebenen Exceptionklassen in den entsprechenden
|
||||
mitgelieferten Dateien.
|
||||
|
||||
4. Ausnahmebehandlung:
|
||||
In der Klasse `Simulation8` sollen nun die Himmelskörper mit Daten aus den gegebenen
|
||||
txt-Dateien initialisiert werden. Dabei sollen zumindest die Sonne sowie die
|
||||
inneren Planeten
|
||||
Merkur, Venus, Erde und Mars vorkommen. Sie können weitere Himmelskörper (siehe txt-Dateien)
|
||||
hinzufügen. Nutzen Sie die Klasse `MassiveForceTreeMap` und ihre Iteratoren, um die
|
||||
Himmelskörper der Simulation zu verwalten. (Kollisionen von Himmelskörpern müssen nicht
|
||||
berücksichtigt werden.)
|
||||
Ändern Sie die Klasse `Simulation8` so, dass sie zwei Kommandozeilenargumente verarbeitet.
|
||||
Das erste Argument ist ein String mit der Angabe des Pfades zum Verzeichnis, wo die
|
||||
entsprechenden txt-Dateien (z.B. `Venus.txt`,`Mercury.txt`,`Earth.txt`) mit den Konfigurationen
|
||||
der Himmelskörper zu finden sind. Die Dateien haben die Namen der Himmelskörper mit Endung `
|
||||
.txt`. Für die Sonne gibt es keine txt-Datei (es wird die Position (0,0,0) angenommen).
|
||||
Das zweite Argument ist ein String mit einer Datumsangabe der Form YYYY-MMM-DD, also z.B.
|
||||
2020-Dec-04, die den Tag der auszulesenden Position und Bewegungsvektor bestimmt. Die Klasse
|
||||
soll beim Auftreten von Problemen bei der Ausführung entsprechende Fehlermeldungen ausgeben und
|
||||
die Ausführung in bestimmten Fällen beenden. Beispiele für Aufrufe im Kommandozeileninterpreter
|
||||
mit entsprechenden Fehlermeldungen (Sie können zum Ausführen das Terminal in IntelliJ nutzen
|
||||
oder die Programmargumente unter `Edit Configurations` angeben):
|
||||
```
|
||||
$ javac Simulation8.java
|
||||
$ java Simulation8 ../states 2021-May-28
|
||||
Running simulation ...
|
||||
$ java Simulation8 ../states
|
||||
Error: wrong number of arguments.
|
||||
$ java Simulation8 ../states 2025-Dec-12
|
||||
Warning: State not available for Earth.
|
||||
Running simulation without Earth.
|
||||
Warning: State not available for Venus.
|
||||
Running simulation without Venus.
|
||||
...
|
||||
$ java Simulation8 ../states-altered 2021-May-28
|
||||
Warning: File ../states-altered/Venus.txt does not have required format.
|
||||
Running simulation without Venus.
|
||||
Warning: File ../states-altered/Mars.txt not found.
|
||||
Running simulation without Mars.
|
||||
Running simulation ...
|
||||
$ java Simulation8 ../states -17
|
||||
Error: State has wrong format (requires YYYY-MM-DD), aborting.
|
||||
$ java Simulation8 blah 2021-May-28
|
||||
Warning: File blah/Earth.txt not found.
|
||||
Running simulation without Earth.
|
||||
Warning: File blah/Venus.txt not found.
|
||||
Running simulation without Venus.
|
||||
...
|
||||
```
|
||||
|
||||
5. Kopieren Sie den Inhalt der Datei `Simulation8.java` in die Datei `Simulation9.java` und bauen
|
||||
Sie `Simulation9` so um, dass anstelle der selbst implementierten Datenstrukturen nur
|
||||
vorgefertigte Klassen aus dem Java-Collection-Framework benutzt werden.
|
||||
|
||||
6. Freiwillige Zusatzaufgabe (ohne Bewertung):
|
||||
Ändern Sie die Klasse `Simulation8` so um, dass ein drittes optionales Kommandozeilenargument
|
||||
verarbeitet werden kann. Dieses gibt an, wieviele Tage simuliert werden sollen. Beispielsweise
|
||||
kann eine zweite Datumsangabe möglich sein, oder die Anzahl an Tagen.
|
||||
Sobald dieser Zeitpunkt in der Simulation erreicht wurde, können die aktuellen Positionen der
|
||||
Himmelskörper mit den in den txt-Dateien angegebenen Positionen verglichen werden (z.B.
|
||||
durch erneutem Aufruf von `readConfiguration` und `draw`). Wie groß sind die Abweichungen
|
||||
der von NASA errechneten Positionen zu den Positionen, die Ihre Simulation liefert?
|
||||
|
||||
### Denkanstöße (ohne Bewertung)
|
||||
|
||||
1. Haben Sie die remove-Methode des Iterators so implementiert, dass der Aufruf keine
|
||||
zusätzliche Suche nach dem zu löschenden Eintrag benötigt?
|
||||
2. Wie verhalten sich die von der Methode `toList()` der Klasse `MassiveForceTreeMap`
|
||||
zurückgelieferten Listen, wenn deren enthaltene Himmelskörper durch `setState` verändert werden?
|
||||
Werden dadurch die Himmelskörper der ursprünglichen `MassiveForceTreeMap`-Objekte auch geändert?
|
||||
(Anmerkung: diesbezüglich gibt es im Aufgabenblatt 6 keine Vorgaben).
|
||||
3. Wie verhalten sich Ihre Iteratoren, wenn Objekte geändert werden?
|
||||
4. Wie kann man durch Einfügen von Zeichen `,` und newlines (`\n`) aus den `txt`-Dateien eine
|
||||
"fehlerhafte" Datei machen, die trotzdem von der Methode akzeptiert wird? Kann man solche Probleme
|
||||
verhindern?
|
||||
|
||||
#### _Punkteaufteilung_
|
||||
|
||||
- Änderung von `next()` von `MassiveIterator`: 0.5 Punkte
|
||||
- Implementierung der Methode `remove()` im Iterator der `MassiveSet`-Sichtweise
|
||||
von `MassiveForceTreeMap`: 2 Punkte
|
||||
- Implementierung der Exceptionklassen und Implementierung von `readConfiguration`
|
||||
in `ReadDataUtil`: 1.5 Punkte
|
||||
- Implementierung von `Simulation8` und `Simulation9`: 1 Punkt

NOTE:
This orbit solution includes non-gravitational perturbations as described in
Micheli et al. (2018): http://dx.doi.org/10.1038/s41586-018-0254-4
The behavior of these accelerations outside the observed data arc from
2017 October 14 to 2018 January 2 can only be assumed. Predictions outside
this time interval, especially prior to October 2017, could be much more
uncertain than reported here.
