Hi Bro,
you have to mention, exactly in which way you wanna see the records in the CSV file. Otherwise if it's a simply ArrayList to CSV file conversion then,follow the simple program below (Still i think, you might have some special requirements, that's what you have to mention specifically):

import java.io.*;
import java.util.ArrayList;

public class CSVWriter{
private static BufferedWriter writeInto = null;
private static File newFile = null;
public static void main(String args[]){
ArrayList holdValues = new ArrayList();
holdValues.add("10");
holdValues.add("20");
holdValues.add("30");
holdValues.add("40");
holdValues.add("50");
holdValues.add("60");
try{
newFile = new File("d:\\Test\\try.csv");
writeInto = new BufferedWriter(new FileWriter(newFile));
for(int index=0;index<holdValues.size();index++){
String temp = (String)holdValues.get(index);
writeInto.write(temp,0,temp.length());
if(index != holdValues.size()-1){
writeInto.write(',');
}
}
}
catch(IOException ex){
System.out.println("Exception in File operation:"+ex);
}
finally{
try{
writeInto.flush();
writeInto.close();
}
catch(IOException exc){
exc.printStackTrace();
}
}
}
}

Thanks Brother,

For one Row it is working perfectly and but with multiple rows coming
from data base, i need to insert one row in one line and next row in another line..

Do you have any code for this?

Any way thanks boss....

Not and advanced question. Moving...

Look through the JavaDoc for that BufferedWriter. See if you find a way to make a new line.

Please search first. You'll find a lot of answers very quickly if you search for "java csv" - you're not the first person who's trying to do something with CSV in Java.

If any have code relevant to this. please send to [e-mail]

Please use the forum, not e-mail.

Please, ease up.

Please read How to Ask Questions on JavaRanch.

No, what is the purpose of having code handed to you? If you want to learn, write some code and ask questions along the way!
