# Aufgabenblatt 6
|
||||||
|
|
||||||
|
## Allgemeine Anmerkungen
|
||||||
|
|
||||||
|
Ihre Lösung für dieses Aufgabenblatt ist bis Montag, 23.5. 11h durch `git commit` und `git push`
|
||||||
|
abzugeben. Mit der Angabe werden die Dateien `MassiveIterable.java`, `MassiveIterator.java`,
|
||||||
|
`MassiveSet.java`, `MassiveForceTreeMap.java`, `Simulation6.java` und `Aufgabe6Test.java`
|
||||||
|
mitgeliefert.
|
||||||
|
|
||||||
|
Wenn Sie zusätzlich zu den gefragten Klassen weitere Klassen definieren, achten Sie darauf, dass
|
||||||
|
die Klassennamen mit `My` beginnen, um Konflikte mit späteren Aufgabenblättern zu vermeiden.
|
||||||
|
|
||||||
|
## Ziel
|
||||||
|
|
||||||
|
Ziel der Aufgabe ist die Anwendung der Konzepte: Iterator, Kopie vs. Sichtweise, Sortieren
|
||||||
|
(siehe Skriptum Seite 91-109).
|
||||||
|
|
||||||
|
## Beschreibung der gegebenen Dateien
|
||||||
|
|
||||||
|
- [MassiveIterable](../src/MassiveIterable.java) ist ein Interface, das iterierbare Objekte mit
|
||||||
|
Elementen vom Typ `Massive` spezifiziert. Verändern Sie diese Datei bitte nicht.
|
||||||
|
- [MassiveIterator](../src/MassiveIterator.java) ist ein Interface, das einen Iterator über
|
||||||
|
Elemente vom Typ `Massive` spezifiziert. Verändern Sie diese Datei bitte nicht.
|
||||||
|
- [MassiveSet](../src/MassiveSet.java) ist ein Interface, das iterierbare Mengen mit
|
||||||
|
`Massive`-Elementen spezifiziert. Verändern Sie diese Datei bitte nicht.
|
||||||
|
- [MassiveForceTreeMap](../src/MassiveForceTreeMap.java) ist das Gerüst für eine Implementierung
|
||||||
|
einer assoziativen Datenstruktur, die ein `Massive`-Objekt mit der auf das Objekt wirkenden Kraft
|
||||||
|
assoziiert.
|
||||||
|
- [Simulation6](../src/Simulation6.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).
|
||||||
|
- [Aufgabe6Test](../src/Aufgabe6Test.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
|
||||||
|
|
||||||
|
Ihre Aufgaben sind folgende:
|
||||||
|
|
||||||
|
**1. Implementieren Sie die Klasse `MassiveForceTreeMap`.**
|
||||||
|
|
||||||
|
Implementieren Sie die Klasse `MassiveForceTreeMap`. `MassiveForceTreeMap` ist wie
|
||||||
|
`BodyForceTreeMap` aufgebaut, mit dem Unterschied, dass der Typ des Schlüssels statt `Body` nun
|
||||||
|
der Typ `Massive` ist. Weiters soll die Klasse Methode `getKeys()` zur Verfügung stellen,
|
||||||
|
die eine `MassiveSet`-Sichtweise auf die Menge der Schlüssel liefert. Änderungen an dem
|
||||||
|
zurückgelieferten `MassiveSet`-Objekt wirken sich auf das zugrunde
|
||||||
|
liegende `MassiveForceTreeMap`-Objekt aus. Die Methode `toList()` liefert dagegen eine
|
||||||
|
unabhängige Liste (Kopie) mit allen Schlüsseln der Map. Für die Implementierung von
|
||||||
|
`MassiveSet` können Sie einen eigenen Klassennamen beginnend mit `My` wählen. Die Definition kann
|
||||||
|
in einer eigenen Datei oder in der Datei `MassiveForceTreeMap.java` erfolgen.
|
||||||
|
|
||||||
|
**2. Adaptieren Sie die Klasse `HierarchicalSystem`:**
|
||||||
|
|
||||||
|
Die Klasse `HierarchicalSystem` soll so geändert werden, dass sie das gegebene
|
||||||
|
Interface `MassiveIterable` implementiert. Die Reihenfolge der vom Iterator gelieferten
|
||||||
|
Elemente ist nicht festgelegt. Sie dürfen für die Implementierung bei Bedarf Ihren Klassen
|
||||||
|
`NamedBodyForcePair` und `HierarchicalSystem` neue, nicht angegebene Methoden hinzufügen.
|
||||||
|
Die Verwendung von Klassen des Java-Collection-Frameworks (z.B. java.util.Stack) ist erlaubt
|
||||||
|
(aber nicht notwendig).
|
||||||
|
|
||||||
|
**3. Implementierung von `Simulation6`:**
|
||||||
|
|
||||||
|
Implementieren Sie die Simulationsschleife unter Verwendung eines Objekts vom Typ
|
||||||
|
`MassiveForceTreeMap`. Die Methode `getKeys()` hilft beim Iterieren der gespeicherten Schlüssel.
|
||||||
|
Kollisionen von Himmelskörpern müssen in dieser Simulation nicht berücksichtigt werden.
|
||||||
|
|
||||||
|
#### _Punkteaufteilung_
|
||||||
|
|
||||||
|
- Implementierung von `MassiveForceTreeMap`: 3 Punkte
|
||||||
|
- Implementierung von `MassiveIterable` in `HierarchicalSystem`: 1.5 Punkte
|
||||||
|
- Implementierung von `Simulation6`: 0.5 Punkte
|
||||||
|
|
||||||
|
- Gesamt: 5 Punkte

# Aufgabenblatt 8
|
||||||
|
|
||||||
|
## Allgemeine Anmerkungen
|
||||||
|
Ihre Lösung für dieses Aufgabenblatt ist bis Montag, 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 Ursprung 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
|
||||||
|

|
||||||
|

|
||||||
|

|
||||||
|

|
||||||
|
Warning: State not available for 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.
|
||||||
|

|
||||||
|
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, wie viele 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
|
||||||
|

|
||||||
|
in `ReadDataUtil`: 1.5 Punkte
|
||||||
|

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.
