问题描述
我的代码需要一些帮助.我需要做的是每次将页面添加到Java Book时，每次都需要在页面上添加不同的数据.我已经尝试了许多不同的方法，但我无法解决！
I need some help with my code. What i need it to do is everytime a page is added to the Java Book different data needs to be on the page every time. I've tried it a number of different ways and i just can't work it out!
这是我的代码:
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());
}
}
}
private class IntroPage implements Printable {
/**

public int print(Graphics g, PageFormat pageFormat, int page) {
//--- Create the Graphics2D object
Graphics2D g2d = (Graphics2D) g;
//--- Translate the origin to 0,0 for the top left corner
g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());

//set title

g2d.drawString(printDate, 350, 120);
//draw to and for strings
g2d.setPaint(Color.darkGray);
g2d.setFont(toForFont);
g2d.drawString(toString, 10, 160);
g2d.drawString(forString, 180, 160);
//draw footer onto page
g2d.setPaint(Color.black);

g2d.drawString(customNotice, 145, 595);
//add image to invoice
Image img;
img = new ImageIcon(this.getClass().getResource("logo.png")).getImage();
g2d.drawImage(img, -10, -10, 180, 84, null);
return (PAGE_EXISTS);
}
}
因此，基本上，我需要做的就是将其他参数传递给print方法，但这是不可能的！它不会以其他方式实现print类！
So basically, all i need to do is pass additional parameters to the print method, but this is impossible! It wouldn't implement the print class other wise!
我已经尝试替换数组等等，我想不起其他任何事情了！
I've tried substituting arrays and a lot more, i can't think of anything else!
推荐答案
您不能向print()添加参数，因为它必须实现接口.
You can't add arguments to the print() as it must implement the interface.
不过，您可以向构造函数添加任意数量的参数，并且可以在您的方法中使用这些参数.
However you can add any number of arguments to the constructor, and these can be used in your method.
bk.append(new IntroPage(arg1, arg2, arg3), PJ.defaultPage());
