How to read a text file using Java

Guys,
Good day!
Please help me how to read a text file using Java and create/convert that text file into XML.
Thanks and God Bless.
Regards,
I-Talk

     public void fileRead(){
             File aFile =new File("myFile.txt");
         BufferedReader input = null;
         try {
           input = new BufferedReader( new FileReader(aFile) );
           String line = null;
           while (( line = input.readLine()) != null){
         catch (FileNotFoundException ex) {
           ex.printStackTrace();
         catch (IOException ex){
           ex.printStackTrace();
     }This code is to read a text file. But there is no such thing that will convert your text file to xml file. You have to have a defined XML format. Then you can read your data from text files and insert them inside your xml text. Or you may like to read xml tags from text files and insert your own data. The file format of .txt and .xml is far too different.

Read lines from text file to java prog

how can I read lines from input file to java prog ?
I need to read from input text file, line after line
10x !

If you search in THIS forum with e.g. read lines from file, you will find answers like this one:
Hi ! This is the answer for your query. This program prints as the output itself reading line by line.......
import java.io.*;
public class readfromfile
public static void main(String a[])
if you search in THIS forum, with e.g. read lines from text file
try{
BufferedReader br = new BufferedReader(new FileReader(new File("readfromfile.java")));
while(br.readLine() != null)
System.out.println(" line read :"+br.readLine());
}catch(Exception e)
e.printStackTrace();
}

How to print a text file using Java

How can I print a text file using Java without converting the output to an image format. Is there anyway I can send the characters in the text file as it is for a print job? I did get a listing doing this ... but that converted the text to an image format before printing....
THanks,.

Hi I had to write a print api from scratch, and I did not convert the output to image. Go and read up on the following code. I know there is a Tutorial on Sun about the differant sections of the snippet.
private void printReport()
     Frame tempFrame = new Frame(getName());
     PrintJob printerJob = Toolkit.getDefaultToolkit().getPrintJob(tempFrame, "Liesltext", null);
     Graphics g = printerJob.getGraphics();
                //I wrote the method below for calculations
     printBasics(g);
     g.dispose();
     printerJob.end();
}This alone wont print it you have to do all the calculations in the printBasics method. And as I said I wrote this from scratch and all I did was research first the tutorial and the white papers
Ciao

How to convert a HTML files into a text file using Java

Hi guys...!
I was wondering if there is a way to convert a HTML file into a text file using java programing language. Likewise I would also like to know if there is a way to convert any type of file (excel, power point, and word) into text using java.
By the way, I really appreciated the help that you guys gave me on my previous topic on how to extract tests from a pdf file.
Thank you....

HTML files are already text files. What do you mean you want to convert them?
I think if you search the web, you can find things for converting those MS Office files to text (or extracting text from them, as I assume you mean).

Changing HTML to text file using java

Hi,
I am doing a project in which i have to read news articles from websites. I have tried XML but for that i need to know which tag has the article in it. Since i have to read from various websites so each site used different tags for different informations.
Is there anyway that i can change an HTML file into a text file using java. Maybe some command that removes all the HTML tags and gives just the information. Is there anything else that anyone would like to recommend?
Thanx
yafis

Maybe something like this:
import java.io.*;
import java.net.*;
import javax.swing.text.*;
import javax.swing.text.html.*;
class GetHTMLText
     public static void main(String[] args)
          throws Exception
          EditorKit kit = new HTMLEditorKit();
          Document doc = kit.createDefaultDocument();
          // The Document class does not yet handle charset's properly.
          doc.putProperty("IgnoreCharsetDirective", Boolean.TRUE);
          // Create a reader on the HTML content.
          Reader rd = getReader(args[0]);
          // Parse the HTML.
          kit.read(rd, doc, 0);
          // The HTML text is now stored in the document
          System.out.println( doc.getText(0, doc.getLength()) );
     // Returns a reader on the HTML data. If 'uri' begins
     // with "http:", it's treated as a URL; otherwise,
     // it's assumed to be a local filename.
     static Reader getReader(String uri)
          throws IOException
          // Retrieve from Internet.
          if (uri.startsWith("http:"))
               URLConnection conn = new URL(uri).openConnection();
               return new InputStreamReader(conn.getInputStream());
          // Retrieve from file.
          else
               return new FileReader(uri);
}

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 to replace a character in a file using awk

Hello,
Does anyone has a sample script to replace a character in a file using awk?
Regards,
Edited by: slsam01 on Jul 15, 2012 12:56 PM

Hi
awk it's not best for this job.
For replace charecter - generaly use tr or sed
Example on awk:
awk -F<old_char> ' { for (i=1; i<NF ;i++ ) printf ( "%s<new_char>", $i ); print $NF }' <file>
#Replace "e" on "a" in /etc/hosts
awk -Fe ' { for (i=1; i<NF ;i++ ) printf ( "%sa", $i ); print $NF }' /etc/hosts
Regards.
PS. Same on *tr"
cat file | tr "e" "a"

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).

How to create and edit a .ini file using java

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

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
          props.store(fos, "");//write the Properties object values to our ini file
          fos.close();//close
}
