Document document = new Document(mFilePath);
Paragraph paragraph = new Paragraph(document);
paragraph.getParagraphFormat().getStyle().getFont().setSize(50);

I use this method to adjust the font size, I don’t know if it is correct。
This method is only valid for some documents. Some documents are invalid。

Document doc = new Document(MyDir + "test2.doc");
FontChanger changer = new FontChanger();
doc.accept(changer);

doc.save(MyDir + "output.docx");

public class FontChanger extends DocumentVisitor
{
///

public int VisitFieldEnd(final FieldEnd fieldEnd)
        {
        //Simply change font name
        ResetFont(fieldEnd.getFont());
        return VisitorAction.CONTINUE;
        }
