Simple linkchecker in jsp

Question

Thanks in advance,
Hello,
in order to build a simple jsp, that enables to check links, i tried to modificate the class "GetURLInfo". The idea is simply reading out the http-header, and print out the Response Message and Code.
Unfortunately i dont know how to make this class able to take the url as a String-Object? Can anyone help me out, please?

import java.net.*;

import java.util.Date;
public class GetURLInfo {
public static void printinfo(URL url) throws IOException {
URLConnection c = url.openConnection(); // Get URLConnection from the URL
c.connect(); // Open a connection to the URL
// Display some information about the URL contents
System.out.println(" Content Type: " + c.getContentType());
System.out.println(" Content Encoding: " + c.getContentEncoding());
System.out.println(" Content Length: " + c.getContentLength());
System.out.println(" Date: " + new Date(c.getDate()));
System.out.println(" Last Modified: " + new Date(c.getLastModified()));
System.out.println(" Expiration: " + new Date(c.getExpiration()));
// If it is an HTTP connection, display some additional information.
if (c instanceof HttpURLConnection) {
HttpURLConnection h = (HttpURLConnection) c;
System.out.println(" Request Method: " + h.getRequestMethod());
System.out.println(" Response Message: " + h.getResponseMessage());
System.out.println(" Response Code: " + h.getResponseCode());
/** Create a URL object, call printinfo() to display information about it. */
public static void main(String[] args) {
try { printinfo(new URL(args[0])); }
catch (Exception e) {
System.err.println(e);
System.err.println("Usage: java GetURLInfo <url>");

I'm not sure if I got you right. Do you want to have another signature for printinfo()?
The solution then is:
public static void printinfo(String urlString) throws IOException, MalformedURLException {
  URL url = new URL(urlString);
}
