Darryl , i don't quite understand that if i copy a file object would i be copying the HTML file or just the file object . It is a bit unclear for me . Maybe if you could just answer that what will be copied : Html or File object , my issue will be resolved .

I am using a jfilechooser .

JFileChooser jFileChooser1=new JFileChooser();


I am getting a
String path=jFileChooser1.getSelectedFile().getPath();
The path is that of an html file .
Now how do i use this to create the same replica of my selected html file in some directory ?

Here's what i did in the command prompt
set classpath=D:\gagan\jdk1.6.0_22\jre\lib\ext;C:\Documents and Settings\g\Desktop\testspace

testspace is the directory where my .java file is kept and ext is the directory where my .jar file is kept .

I saw the tutorial and i know how to set the classpath as well but this hasn't solve the problem .

I have used a third party api htmlparser.jar and i have kept that jar file in jdk/jre/lib/ext . Then i wrote the following code in my .java file
import org.htmlparser.beans.*;
import org.htmlparser.util.ParserException;
//and much more imports
Class Xyz { Xyz { StringBean b=new StringBean } }
Now when i compiled the code it gave me no errors but when i tried to run the code it gave me NoClassDefFoundError . for that i checked out the .jar file and to the best of my knowledge it's ok . So why am i getting this error ?

I am currently working on a program that involves huge calculations like (345324523452345245345*4543563456456545456) .
Should BigDecimal suffice for this ? Also i sometimes need to convert them into double for example Math.pow(BigDecimalObject.doubleValue(),2)
Will there be a huge probability of an error during such conversions ?

Actually paul the thing is my program generates somewhere around 1000 values in an arraylist so just want to know that how do i connect my program with excel . Manually entering values and generating graph would be difficult .

I have to take some values close to 1000 and then plot a graph in excel , so i was wondering if somebody could tell me what exactly to study ?
Thanks in advance .

Thanks a lot Rob Spoor .

To be specific does the interface Runnable extends Object class ?? According to me it's no but somebody put a doubt in my head ,so please answer . Thank you .

@ Darryl Don't you think that i added the textarea through a JScrollPane ?

My problem is that the textarea in the local inner class is not getting the value that i type when i run the code and click the get from the menu . It is supposed to take the value from the textarea and then print it on command line .

Thanks i will try that . Thank you man .

Hi , i want to open a .c file in a textarea in text format . How do i do that ?

Hello everyone , i am trying to make a code obfuscator and one of the techniques i encountered was preventing de-compilation by appending extra instructions afte return instruction . I have no idea regarding this and would love it if anyone can point me regarding what to read or which api i need to lookup . Thanks in advance . Any other ideas whch can prevent decompilation are welcome .
