How to download a file from a website and save it locally

Question

Hi people,
I have a number of URLs at hand that point to certain class files, e.g.
http://www.mywebsite.com/classes/MyClass.class
What i would like to do is to download MyClass.class into a temporary folder on the local disk. Does anyone know how to do this? I've read about HttpURLConnection etc., but its all very confusing!
Cheers,
JG

Answer 1

you need to create a URL to the url
URL url = new URL("http://www.mywebsite.com/classes/MyClass.class");
HttpURLConnection c = (HttpURLConnection)url.openConnection();
then you need to acquire an input stream from the connection. Roughly this is
InputStreamReader r = (InputStreamReader)c.getInputStream();
FileWriter w = new FileWriter("c:\\temp\\" + name);
int b;
while((b = r.read()) != -1) {
w.write(b);
close all streams
something like this - will let you work out the rest..dont forget to try/catch all the IO exceptions.
