// The path to the documents directory.
String dataDir = Utils.getDataDir(AddPDFBookmarks.class);
// Instantiate a new workbook.
Workbook workbook = new Workbook();
// Get the worksheets in the workbook.

// Add a sheet to the workbook.
worksheets.add("1");
// Add 2nd sheet to the workbook.
worksheets.add("2");
// Add the third sheet.
worksheets.add("3");
// Get cells in different worksheets.
Cell cellInPage1 = worksheets.get(0).getCells().get("A1");
Cell cellInPage2 = worksheets.get(1).getCells().get("A1");
Cell cellInPage3 = worksheets.get(2).getCells().get("A1");
// Add a value to the A1 cell in the first sheet.
cellInPage1.setValue("a");
// Add a value to the A1 cell in the second sheet.
cellInPage2.setValue("b");
// Add a value to the A1 cell in the third sheet.
cellInPage3.setValue("c");
// Create the PdfBookmark entry object.
PdfBookmarkEntry pbeRoot = new PdfBookmarkEntry();
// Set its text.
pbeRoot.setText("root");
// Set its destination source page.
pbeRoot.setDestination(cellInPage1);
// Set the bookmark collapsed.
pbeRoot.setOpen(false);
// Add a new PdfBookmark entry object.
PdfBookmarkEntry subPbe1 = new PdfBookmarkEntry();
// Set its text.
subPbe1.setText("1");
// Set its destination source page.
subPbe1.setDestination(cellInPage2);
// Add another PdfBookmark entry object.
PdfBookmarkEntry subPbe2 = new PdfBookmarkEntry();
// Set its text.
subPbe2.setText("2");
// Set its destination source page.
subPbe2.setDestination(cellInPage3);
// Create an array list.
ArrayList subEntryList = new ArrayList();
// Add the entry objects to it.
subEntryList.add(subPbe1);
subEntryList.add(subPbe2);
pbeRoot.setSubEntry(subEntryList);
// Set the PDF bookmarks.
PdfSaveOptions options = new PdfSaveOptions();
options.setBookmark(pbeRoot);
// Save the PDF file.
workbook.save(dataDir, options);
