Hi All...
Pls help me in creating and editing an .ini file using java...
thanks in advance

Let's assume the ini file is a mapping type storage (key=value) so lets use Properties object. (works with java 1.4 & up)

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Properties;
public class Test {
     private static Properties props;
     public static void main(String[] args) throws IOException {
          File file = new File("test.ini");//This is out ini file
          props = new Properties();//Create the properties object
          read(file);//Read the ini file
          //Once we've populated the Properties object. set/add a property using the setProperty() method.
          props.setProperty("testing", "value");
          write(file);//Write to ini file

How to Write in bold to a file using java I/O classes?

Hi,
Using I/O classes I want to prepare a .doc file in which some text will be there. I want that text to be formatted. Like some text I want to be bold. Some text to be italic. How can I write bold/Italic text to the file using java I/O classes.
Thanks
Prashant

By .doc file, I'm assuming you mean an MS Word document, yes? (fyi, Word Perfect also used the .doc extension)
The .doc format is proprietary to Microsoft and isn't documented by them. In order to output a file in .doc format you'd have to understand that format correctly, otherwise MS Word will spit out it's tongue at you, call you names, and maybe send the Microsoft Police to "audit" your PC Software Licensing.
Fortunately for you there is an open source project to demangle the microsoft file formats. See http://jakarta.apache.org/poi/ and especially pay attention to the HDF project (Horrible Document Format).

You should update your DOM document to represent the changes that you want made.
Then, using the Transformation API you simply transform your document onto a stream representing your file. Something like this:
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
// TODO - set indentation amount!
Source source = new DOMSource(dom);
Result result = new StreamResult(file);
transformer.transform(source, result);Hope this helps.
