Can anyone pls tell me how to copy a file from one folder to another folder

Hi senthilkumar
I hope I help you:
copy file:

File file = new File("path of source file");
if(file.exists){
FileInputStream fis = new FileInputStream(file);
FileOutputStream fos = new FileOutputStream("path of new file");
byte[] buff = new byte[fis.available()];
fis.read(buff);
fos.write(buff);
}

Thanks for ur reply.ur code is correct for one text file.
I have a folder which contains lot of text files and image files.
I want to copy all files from one folder to another.
Can any one pls help me?

senthikumar, you have already been asked once to change your display name to conform to the JavaRanch Naming Policy. I must warn you that if you do not comply, your account will be closed.
You can change your name here.
As for Kia's code, it has one fatal error: available() doesn't do what you think it does.
Have a look at this example for a copy method that works.
To copy an entire directory, use the methods of java.io.File to get a list of the directory contents and copy each file individually.

Thank Joe Ess. I think your example very good.
