copying fles in java

Hi,
 the code below takes a file (C:\\ANT\\Source\\Waterfall.jpg) and creates a byte file of it and stores it at c:\\ANT\\Destination\\file1.
Right now, the source file (Waterfall.jpg) must exist at c:\ANT\Source, also file1 need not exist at c:\ANT\Destination but it has to be in the argument of FileOutputStream or else I get a runtime error ;
Exception in thread "main" java.io.FileNotFoundException: c:\ANT\Destination (Access is denied)
        at java.io.FileOutputStream.open(Native Method)
        at java.io.FileOutputStream.<init>(FileOutputStream.java:179)
        at java.io.FileOutputStream.<init>(FileOutputStream.java:70)
        at CopyBytes.main(CopyBytes.java:17)
////////////////////////////////////
what i am trying to do is write an application that takes whatever is stored at c:\ANT\source converts it/them to corresponding byte files and store the byte files at c:\ANT\Destination.

any help appreciated.
thanks

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;


public class CopyBytes {
    public static void main(String[] args) throws IOException {
        FileInputStream in = null;
        FileOutputStream out = null;
        try {
            in = new FileInputStream("C:\\ANT\\Source\\Waterfall.jpg");
            out = new FileOutputStream("c:\\ANT\\Destination\\file1");
            int c;

            while ((c = in.read()) != -1) {
                out.write(c);
            }

        } finally {
            if (in != null) {
                in.close();
            }
            if (out != null) {
                out.close();
            }
        }
    }
}
