Michael:
You're right. Copy / paste for the loose; I read right over it. :(
corrected code:
package s;
import java.io.FileWriter;
import java.io.InputStream;
import java.io.IOException;
import java.io.FileOutputStream;
import java.net.URL;
import java.net.URLConnection;
import java.net.MalformedURLException;
public class Main
{
public static void main(String[] args) throws IOException
{
URL url = new URL("
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2947364/pdf/msb201055.pdf?tool=pmcentrez
");
URLConnection con = url.openConnection();
InputStream in = con.getInputStream();
FileOutputStream out = new FileOutputStream("C:/My.pdf");
int next = 0;
while ( ( next = in.read() ) != -1 ) {
out.write(next);
}
out.flush();
out.close();
in.close();
}
}

Often people, especially computer engineers, focus on the machines. They
think, "By doing this, the machine will run faster. By doing this, the
machine will run more effectively. By doing this, the machine will something
something something." They are focusing on machines. But in fact we need to
focus on humans, on how humans care about doing programming or operating the
application of the machines. We are the masters. They are the slaves. --
