Correct me where I'm going wrong.
I'm have written a program in Java which will get list of files from two different directories and make two (Java list) with the file names. I want to transfer the both the list (downloaded files list and Uploaded files list) to an
excel.
What the result i'm getting is those list are transferred row wise. I want them in column wise.
Given below is the code:
public class F {
static List<String> downloadList = new ArrayList<>();
static List<String> dispatchList = new ArrayList<>();
public static class FileVisitor extends SimpleFileVisitor<Path> {
@Override
public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) throws IOException {
String name = file.toRealPath().getFileName().toString();
if (name.endsWith(".pdf") || name.endsWith(".zip")) {
downloadList.add(name);
}
if (name.endsWith(".xml")) {
dispatchList.add(name);
}
return FileVisitResult.CONTINUE;
}
}
public static void main(String[] args) throws IOException {
try {
Path downloadPath = Paths.get("E:\\report\\02_Download\\10252013");
Path dispatchPath = Paths.get("E:\\report\\01_Dispatch\\10252013");
FileVisitor visitor = new FileVisitor();
Files.walkFileTree(downloadPath, visitor);
Files.walkFileTree(downloadPath, EnumSet.of(FileVisitOption.FOLLOW_LINKS), 1, visitor);
Files.walkFileTree(dispatchPath, visitor);
Files.walkFileTree(dispatchPath, EnumSet.of(FileVisitOption.FOLLOW_LINKS), 1, visitor);
System.out.println("Download File List" + downloadList);
System.out.println("Dispatch File List" + dispatchList);
F f = new F();
f.UpDown(downloadList, dispatchList);
} catch (Exception ex) {
Logger.getLogger(F.class.getName()).log(Level.SEVERE, null, ex);
}
}
int rownum = 0;
int colnum = 0;
HSSFSheet firstSheet;
Collection<File> files;
HSSFWorkbook workbook;
File exactFile;
{
workbook = new HSSFWorkbook();
firstSheet = workbook.createSheet("10252013");
Row headerRow = firstSheet.createRow(rownum);
headerRow.setHeightInPoints(40);
}
public void UpDown(List<String> download, List<String> upload) throws Exception {
List<String> headerRow = new ArrayList<>();
headerRow.add("Downloaded");
headerRow.add("Uploaded");
List<List> recordToAdd = new ArrayList<>();
recordToAdd.add(headerRow);
recordToAdd.add(download);
recordToAdd.add(upload);
F f = new F();
f.CreateExcelFile(recordToAdd);
f.createExcelFile();
}
void createExcelFile() {
FileOutputStream fos = null;
try {
fos = new FileOutputStream(new File("E:\\report\\Download&Upload.xls"));
HSSFCellStyle hsfstyle = workbook.createCellStyle();
hsfstyle.setBorderBottom((short) 1);
hsfstyle.setFillBackgroundColor((short) 245);
workbook.write(fos);
} catch (Exception e) {
}
}
public void CreateExcelFile(List<List> l1) throws Exception {
try {
for (int j = 0; j < l1.size(); j++) {
Row row = firstSheet.createRow(rownum);
List<String> l2 = l1.get(j);
for (int k = 0; k < l2.size(); k++) {
Cell cell = row.createCell(k);
cell.setCellValue(l2.get(k));
}
rownum++;
}
} catch (Exception e) {
} finally {
}
}
}
(The purpose is to verify the files Downloaded and Uploaded for the given date)
Thanks.
