u can add ordered and unordered lists to a PDF document using IText. List are represented by the class 
com.itextpdf.text.List. List items are represented by the classcom.itextpdf.text.ListItem.
Here is a simple code example:
import com.itextpdf.text.*;
import com.itextpdf.text.pdf.PdfWriter;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class ListExample {
    public static void main(String[] args) {
        Document document = new Document();
        try {
            PdfWriter.getInstance(document,
                new FileOutputStream("List.pdf"));
            document.open();
            List orderedList = new List(List.ORDERED);
            orderedList.add(new ListItem("Item 1"));
            orderedList.add(new ListItem("Item 2"));
            orderedList.add(new ListItem("Item 3"));
            document.add(orderedList);
            List unorderedList = new List(List.UNORDERED);
            unorderedList.add(new ListItem("Item 1"));
            unorderedList.add(new ListItem("Item 2"));
            unorderedList.add(new ListItem("Item 3"));
            document.add(unorderedList);
            document.close();
        } catch (DocumentException e) {
            e.printStackTrace();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}

Roman and Greek Numerals
You can create lists with roman and greek numerals too. To do this, use the
com.itextpdf.text.RomanList and com.itextpdf.text.GreekList classes. Here is an example:import com.itextpdf.text.*;
import com.itextpdf.text.pdf.PdfWriter;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class List2Example {
    public static void main(String[] args) {
        Document document = new Document();
        try {
            PdfWriter.getInstance(document,
                new FileOutputStream("List2.pdf"));
            document.open();
            RomanList romanList = new RomanList();
            romanList.add(new ListItem("Item 1"));
            romanList.add(new ListItem("Item 2"));
            romanList.add(new ListItem("Item 3"));
            document.add(romanList);
            GreekList greekList = new GreekList();
            greekList.add(new ListItem("Item 1"));
            greekList.add(new ListItem("Item 2"));
            greekList.add(new ListItem("Item 3"));
            document.add(greekList);
            document.close();
        } catch (DocumentException e) {
            e.printStackTrace();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}

ZapfDingbatsList
IText has a special list implementation that uses the ZapfDingbats font. It's constructor takes two parameters: The number of the symbol to use as item bullet, and the indentation of the text after the bullet (space between bullet and text). Here is a code example:
import com.itextpdf.text.*;
import com.itextpdf.text.pdf.PdfWriter;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class List3Example {
  public static void main(String[] args) {
    Document document = new Document();
    try {
      PdfWriter.getInstance(document,
            new FileOutputStream("List3.pdf"));
      document.open();
      ZapfDingbatsList zapfDingbatsList1 =
            new ZapfDingbatsList(40, 15);
      zapfDingbatsList1.add(new ListItem("Item 1"));
      zapfDingbatsList1.add(new ListItem("Item 2"));
      zapfDingbatsList1.add(new ListItem("Item 3"));
      document.add(zapfDingbatsList1);
      ZapfDingbatsList zapfDingbatsList2 =
            new ZapfDingbatsList(43, 30);
      zapfDingbatsList2.add(new ListItem("Item 1"));
      zapfDingbatsList2.add(new ListItem("Item 2"));
      zapfDingbatsList2.add(new ListItem("Item 3"));
      document.add(zapfDingbatsList2);
      ZapfDingbatsList zapfDingbatsList3 =
            new ZapfDingbatsList(47, 45);
      zapfDingbatsList3.add(new ListItem("Item 1"));
      zapfDingbatsList3.add(new ListItem("Item 2"));
      zapfDingbatsList3.add(new ListItem("Item 3"));
      document.add(zapfDingbatsList3);
      document.close();
    } catch (DocumentException e) {
      e.printStackTrace();
    } catch (FileNotFoundException e) {
      e.printStackTrace();
    }
  }
}
