How do I get response header from HTTP request?


package org.kodejava.example.net;

import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

public class HttpResponseHeaderDemo {
public static void main(String[] args) {
try {
URL url = new URL("http://www.kodejava.org/index.html");
URLConnection connection = url.openConnection();

Map responseMap = connection.getHeaderFields();
for (Iterator iterator = responseMap.keySet().iterator(); iterator.hasNext();) {
String key = (String) iterator.next();
System.out.print(key + " = ");

List values = (List) responseMap.get(key);
for (int i = 0; i < values.size(); i++) {
Object o = values.get(i);
System.out.print(o + ", ");
}
System.out.println("");
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
