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?

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

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
    // step 4
    XMLWorkerHelper.getInstance().parseXHtml(writer, document,
            new FileInputStream(HTML));
    // step 5

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 available in case you need support for images, special fonts, and so on.
