Copying Files

People,

Which class, or set of classes facilitate the copying of files ? Please note that I dont really want to open a file, read it in and write its contents to another file, i want to actually do a proper copy.

There must be a class that will allow

myObj.copyFile("from", "to");
// or maybe from and to would be File objects.

Please tell me that there is a class that will do this. A code snippet would be helpful too .

Cheers

Mehdi

In Java there is no way to copy a file without opening it. Other solutions are platform dependend and not possible in Java.
Here is a simple Example of the copyFile() method:

public void copyFile(String src, String dest) throws IOException
{
InputStream is = new FileInputStream(src);
OutputStream os = new FileOutputStream(dest);
byte[] buffer = new byte[0xffff]; // buffer size = FFFF hex
int nbytes;

while ((nbytes = is.read(buffer)) != -1)
{
os.write(buffer, 0, nbytes);
} // while ((nbytes = is.read(buffer)) != -1)

is.close();
os.close();
} // public void copyFile(String)
