> import org.apache.http.client.HttpClient;
> import org.apache.http.client.methods.HttpGet;
> import org.apache.http.impl.client.DefaultHttpClient;
> public class BadRequest {
> public static void main(String[] args) {
> try {
> HttpClient httpclient = new DefaultHttpClient();
> HttpGet httpget = new HttpGet("http://www.edu.mah.se/KK3231/syllabus/");
> System.out.println(httpclient.execute(httpget).getStatusLine().getStatusCode());
> } catch (IOException e) {
> e.printStackTrace();
> }
> }
> }
> raises an exception as follows:
> % java BadRequest
