Reading binary file from URLConnection

Question

I'm trying to read a binary file from a URLConnection. When I test it with a text file it seems to work fine but for binary files it doesn't. I'm using the following mime-type on the server when the file is send out:

application/octet-stream

But so far nothing seems to work. This is the code that I use to receive the file:

file = File.createTempFile( "tempfile", ".bin");
file.deleteOnExit();

URL url = new URL( "http://somedomain.com/image.gif" );

URLConnection connection = url.openConnection();

BufferedReader input = new BufferedReader( new InputStreamReader( connection.getInputStream() ) );

Writer writer = new OutputStreamWriter( new FileOutputStream( file ) );

int c;

while( ( c = input.read() ) != -1 ) {

   writer.write( (char)c );
}

writer.close();

input.close();

Answer 1

This is how I do it,

input = connection.getInputStream();
byte[] buffer = new byte[4096];
int n;

OutputStream output = new FileOutputStream( file );
while ((n = input.read(buffer)) != -1) 
{
    output.write(buffer, 0, n);
}
output.close();
