I am using iText in Java to convert a HTML to PDF.

I want a particular paragraph which has some words as Bold and some as Bold+Underlined to be passed as a string to the Java code and to be converted to PDF using the iText library.

I am unable to find a suitable method for this. How should I do this?

First feed your HTML into this demo: demo.itextsupport.com/xmlworker Then hit transform. Do you get the desired result? If so, I'll show you the code. – Bruno Lowagie
Yes, it worked. Can you please share the code? – Anuranjan
See my answer. You may want to try all the examples before writing your own code. – Bruno Lowagie
I am following your book Bruno. It's great to hear from you. – Anuranjan
If you refer to "iText in Action": the HTML to PDF part needs to be replaced. If you refer to "The ABC of PDF", that's a work in progress. Once that book is finished, I'll use the XML Worker examples as the basis for a book about templates for PDF. – Bruno Lowagie

If you want to convert XHTML to PDF, you need iText + XML Worker.

You can find a number of examples here: http://itextpdf.com/sandbox/xmlworker

The most simple examples looks like this:

public void createPdf(String file) throws IOException, DocumentException {
    // step 1
    Document document = new Document();
    // step 2
    PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
    // step 3
    document.open();
    // step 4
    XMLWorkerHelper.getInstance().parseXHtml(writer, document,
            new FileInputStream(HTML));
    // step 5
    document.close();
}

Note that the HTML file is passed as a FileInputStream in this case. You want to pass a String. This means you'll have to do something like this:

XMLWorkerHelper.getInstance().parseXHtml(writer, document,
        new StringReader("<p>The <b>String</b> I want to render to PDF</p>"));

There are more complex examples in the Sandbox in case you need support for images, special fonts, and so on. For instance this example will convert XHTML to a series of iText objects instead of rendering them to a page rightaway.
