Example:

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

for (int i = 0; i <= 100; i++) {
    builder.write("Some text " + i);

    builder.insertFootnote(FootnoteType.FOOTNOTE, "Footnote text " + i);
    builder.insertFootnote(FootnoteType.FOOTNOTE, "Footnote text " + i, "242");

Example:

// Create a new document and append some text that we will reference with a footnote
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.write("Main body text.");

// Add a footnote and give it text, which will appear at the bottom of the page
Footnote footnote = builder.insertFootnote(FootnoteType.FOOTNOTE, "Footnote text.");

// This attribute means the footnote in the main text will automatically be assigned a number, "1" in this instance
// The next footnote will get "2"
Assert.assertTrue(footnote.isAuto());

// We can edit the footnote's text like this
// Make sure to move the builder back into the document body afterwards
builder.moveTo(footnote.getFirstParagraph());
builder.write(" More text added by a DocumentBuilder.");
builder.moveToDocumentEnd();

Assert.assertEquals(footnote.getParagraphs().get(0).toString(SaveFormat.TEXT).trim(), "Footnote text. More text added by a DocumentBuilder.");

builder.write(" More main body text.");
footnote = builder.insertFootnote(FootnoteType.FOOTNOTE, "Footnote text.");

// Substitute the reference number for our own custom mark by setting this variable, "IsAuto" will also be set to false
footnote.setReferenceMark("RefMark");
Assert.assertFalse(footnote.isAuto());

// This bookmark will get a number "3" even though there was no "2"
builder.write(" More main body text.");
footnote = builder.insertFootnote(FootnoteType.FOOTNOTE, "Footnote text.");
Assert.assertTrue(footnote.isAuto());
