Die Parameterübergabe an die print-Methode (JAVA)
Brauche ich etwas Hilfe mit meinem code. Was ich brauche, es zu tun ist, jedesmal, wenn eine Seite Hinzugefügt, um die Java-Buch, das verschiedene Daten muss auf der Seite jeder Zeit. Ich habe es ausprobiert eine Reihe von verschiedenen Möglichkeiten, und ich kann einfach nicht funktionieren it out!
Hier ist mein code:
dataBase data = new dataBase();
int userCountAmount = data.getAmountOfUsers();
Book bk = new Book();
PrinterJob PJ = PrinterJob.getPrinterJob();
String[] pupilName = new String[userCountAmount];
String[] parentsName = new String[userCountAmount];
int parCount = 0;
int pupCount = 0;
public void print2() {
System.out.println(pupilName.length);
System.out.println(parentsName.length);
System.out.println(userCountAmount);
String[] custData = processData(data.getAllCustomers());
PageFormat portrait = PJ.defaultPage();
int pupNameCount = 0;
int parNameCount = 0;
portrait.setOrientation(PageFormat.PORTRAIT);
for (int i = 0; i < userCountAmount; i++) {
pupilName[i] = custData[pupNameCount];
parentsName[i] = custData[parNameCount];
System.out.println(custData[pupNameCount] + " " + custData[parNameCount]);
pupNameCount = pupNameCount + 13;
parNameCount = parNameCount + 13;
bk.append(new IntroPage(), PJ.defaultPage());
parCount++;
pupCount++;
System.out.println(parCount+" " + pupCount);
}
// setWindow();
//PageFormat PF = PJ.pageDialog(PJ.defaultPage());
PJ.setPageable(bk);
// PJ.setPrintable((Printable) this);
boolean doPrint = PJ.printDialog();
//JOptionPane.showMessageDialog(null, doPrint);
if (doPrint) {
try {
PJ.print();
} catch (PrinterException ex) {
JOptionPane.showMessageDialog(null, ex.getMessage());
}
}
}

Also im Grunde alles, was ich tun müssen, ist die übergabe weiterer Parameter an die print-Methode, aber das ist unmöglich! Es wäre nicht die Umsetzung der print-Klasse andere Weise!
Habe ich versucht zu ersetzen-arrays und eine Menge mehr, ich kann nicht an nichts anderes denken!
Du musst angemeldet sein, um einen Kommentar abzugeben.
Können Sie nicht Argumente an die print () - wie muss das interface implementieren.
Aber Sie können eine beliebige Anzahl von Argumenten an den Konstruktor, und diese können verwendet werden, in Ihrer Methode.
Könnten Sie Felder hinzufügen, um die Klasse
IntroPage
. Dann, wenn Sie erstellenIntroPage
pass geeignete Argumente zur Initialisierung Ihrer fileds. Und später, inprint()
verwenden, können Sie die Daten von Ihrem fileds.
