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).

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

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.File;
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
     public static void read(File file) throws IOException {
          FileInputStream fis = new FileInputStream(file);//Create a FileInputStream
          props.load(fis);//load the ini to the Properties file
          fis.close();//close
     public static void write(File file) throws IOException {
          FileOutputStream fos = new FileOutputStream(file);//Create a FileOutputStream

Since the word "TEXT" is formed of 4 letters, you would read the text file 4 bytes by four bytes. Wrong on two counts. First, the file may not be encoded 1 byte per character. It could be utf-16 in which case it would be two byte per character. Second, even if it were 1 byte per character, the string "Text" may not start on a 4 byte boundary.
Consider a FileInputStream object "fis" that points to your text file. use fis.read(byte[] array, int offset, int len) to read every four bytes. Convert the "TEXT" String into a byte array "TEXT".getBytes(), and yous the Arrays class to compare the equality of the read bytes with your "TEXT".getBytes()Wrong since it relies on my second point and will fail when fis.read(byte[] array, int offset, int len) does not read 4 bytes (as is no guaranteed to). Check the Javadoc. Also, the file may not be encoded with the default character encoding.
The problem is easily solved by reading a line at a time using a BufferedReader wrapping an InputStreamReader wrapping a FileInputStream and specifying the correct character encoding.

How do I translate word perfect old files for my new iMac?

How do I translate Word Perfect old files for my new iMac? They are transferred from a 13-year-old Dell. My McLink did not work.
Thanks.

The current version of the free LibreOffice continues to support Word Perfect documents. OpenOffice had to drop this support due to licensing issues. LO installs in two places: /Applications and your local Library/Application Support directory. Simple to install. Simple to remove. Good PDF documentation from their site. It is a capable MS Office replacement.
I just opened a wpd legal deposition in LO and it looked fine.
