java ArrayList和itextpdf，表
我有一个30行的表和一个充满字符串的数组列表。表有两列，第一列类似于公司名称，第二列我需要从列表中写入字符串，第二列的每一行应该有10个元素，我该怎么做
PDF输出应该是这样的：
Company name |||| DESTINATION
AirFrance |||| Tokio,London,Istanbul,New Nork,Paris,Vienna,OSLO,Belgrade,Budapest,Amsterdam.
每个公司应该从列表中读取10个目的地
这可能是一件简单的事情，我只是看不到。我试图计算列表元素，并以某种方式对其进行分区，但没有成功
顺便说一下，我使用itextpdf库，从excel中读取这些数据
以下是代码：
public class ReadExcel {
private String inputfile;
private List<Avio> avioni;
public ReadExcel() {
this.avioni = new ArrayList<Avio>();
}
public List<Avio> getAvioni() {
return avioni;
}
public void setAvioni(List<Avio> avioni) {
this.avioni = avioni;
}
public String getInputfile() {
return inputfile;
}
public void setInputfile(String inputfile) {
this.inputfile = inputfile;
}
public void citaj(String naziv) {
Avio a = new Avio();
try {
Workbook w = Workbook.getWorkbook(new File(naziv));
Sheet sheet = w.getSheet(0);
// System.out.println(sheet.getRows());
for (int i = 1; i < sheet.getRows(); i++) {
Avio tmpAvio = new Avio();
tmpAvio.setDrzava(sheet.getCell(0, i).getContents());
System.out.println();
tmpAvio.setNazivKomp(sheet.getCell(1, i).getContents());
tmpAvio.setVlasnik(sheet.getCell(2, i).getContents());
tmpAvio.setBrAviona(Integer.parseInt(sheet.getCell(3, i)
.getContents()));
tmpAvio.setGod(Integer.parseInt(sheet.getCell(4, i)
.getContents()));
tmpAvio.setDatum(sheet.getCell(6,i).getContents());
tmpAvio.setModelAviona(sheet.getCell(7,i).getContents());
tmpAvio.setKapetan(sheet.getCell(8,i).getContents());
tmpAvio.setJMBG(sheet.getCell(9,i).getContents());
tmpAvio.setIskustvo(sheet.getCell(10,i).getContents());
tmpAvio.setBrPutnika(sheet.getCell(11,i).getContents());
tmpAvio.setLet(sheet.getCell(12,i).getContents());
avioni.add(tmpAvio);
}
Sheet sheet1 = w.getSheet(1);
List<String> destinacije = new ArrayList<String>();
for (int i = 0; i < sheet1.getRows(); i++) {
for (int j = 0; j < sheet1.getColumns(); j++) {
destinacije.add(sheet1.getCell(j, i).getContents());
System.out.println(sheet1.getCell(j,i).getContents()+i+","+j);
}
avioni.get(i).setDestinacije(destinacije);
System.out.println(avioni.get(i));
}
}
