CreatePDFiText.java
import com.lowagie.text.Document;
import com.lowagie.text.Font;
import com.lowagie.text.FontFactory;
import com.lowagie.text.PageSize;
import com.lowagie.text.Paragraph;
import com.lowagie.text.Chunk;
import com.lowagie.text.pdf.PdfWriter;
import com.lowagie.text.pdf.PdfContentByte;
public class CreatePDFiText {
	public static void main(String[] args) {
	    try {
		Document document = new Document(PageSize.
                A4, 50, 50, 50, 50);
		PdfWriter writer = PdfWriter.getInstance
                (document, new FileOutputStream("C:\\my.pdf"));
                document.open();
                // create a chunk object using chunk class
                of itext library.
		Chunk underlined = new Chunk("This is 
                sample pdf file created by : ");
		// set the distance between text and line.
		underlined.setTextRise(8.0f);
		// set the width of the line, 'y' position,
               color and design of the line
		underlined.setUnderline(new Color(0x00, 0x00, 
                0xFF),0.0f, 0.2f, 3.0f, 0.0f,
                   PdfContentByte.LINE_CAP_PROJECTING_SQUARE);
		// finally add object to the document.
		document.add(underlined);
                document.add(new Paragraph("Mahendra Singh",
                FontFactory.getFont(FontFactory.COURIER, 14, 
                Font.BOLD, new Color(255, 150, 200))));;
		document.close();
	     } 
	     catch (Exception e2) {
			System.out.println(e2.getMessage());
	     }
	}
}
