salut,

j'ai lu un fichier owl et je voudrais extraire une chaine de caractère de ce fichier et la mettre dans un tableau en java, pour les incorporer à un JComboBox.
Mais même en utilisant la classe readLine et Tokenizer je n'arrive pas à faire l'extraction. Pourriez vous m'aider?
Merci d'avance.

Salut,

Bien volontiers, mais la question demande à être un peu plus développée:

-Format des lignes lues,
-Ce qu'on doit extraire et mettre dans le tableau qui permettra de créer la JcomboBox,
-La version Java utilisée...

Sans oublier la partie du code concernée.

Cordialement,

Dan

salut,
j'ai lu le fichier owl(exemple:http://osm.cs.byu.edu/CS652s04/ontologies/OWL/carads.owl).

voila la partie du code qui lit et affiche le contenu de fichier ligne par ligne:

private void LoadFile(String fileURL){
try{
BufferedReader buff = new BufferedReader(new FileReader(fileURL));
try {
String line;
while ((line = buff.readLine()) != null) {
System.out.println(line);
}
} finally {
// dans tous les cas, on ferme nos flux
buff.close();
}
} catch (IOException ioe) {
// erreur de fermeture des flux
System.out.println("Erreur --" + ioe.toString());

}
}
je veux extraire les deux chaines (voir le fichier ):maxCardinality et minCardinality, et les mettre dans le tableau qui permettra de créer la JcomboBox,

j'ai utilisé jdk-1.5.

merci.

Salut,

La page : (exemple:http://osm.cs.byu.edu/CS652s04/ontologies/OWL/carads.owl).
n'existe pas.
Le mieux serait que tu me donnes la description de la ligne lue (ce que tu obtiens en lisant une ligne : System.out.println(line); )
