Problem saving gif file over the net

Question

I am using a simple loop to save files using a URL Connection. It grabs html files fine and they look right but when I used to to download an animated gif it had an error. It saved the file but when I tried to open the image I got a "drawing failed" message.
I compared it to the working image and the sizes were identical. I also compared the characters in notepad and the beginning and end characters were identical. I looked at the preview in "My Computer" when you select it and it drew only the first line or so. This makes me believe it is a problem with how it switches lines when saving. I checked the ends of the lines though and they also seem identicall. Any ideas? Here is the code. Thankyou.
FileWriter fileName = new FileWriter(saveFileName);
BufferedReader in = new BufferedReader(
new InputStreamReader(
newConnection.getInputStream()
BufferedWriter out = new BufferedWriter(fileName);
for (;;) {
int data = in.read();
// Check for EOF
if (data == -1) break;
else {
System.out.print ( (char) data);
out.write(data);
}

GIF files are binary files and can be corrupted if you use the Reader and Writer classes. Use the *Stream classes, like FileInputStream and FileOutputStream.
