Poor man's wget for Windows

Windows not only is an awfully stinking mastodon, but it even lacks the most basic tools commonly available on Linux, such as telnet and wget.

I have found a bare bones wget implementation for Java and duly simplified (I love to strip away all useless exception handling)

import java.io.InputStream;
import java.io.DataInputStream;
import java.io.BufferedInputStream;
import java.net.*;

public class JGet {
    public static void main(String[] args) throws Exception {
        if ((args.length != 1)) {
           System.err.println("\nUsage: java JGet [urlToGet]");
        String url = args[0];
        URL u;
        InputStream is = null;
        DataInputStream dis;
        String s;
        try {
           u = new URL(url);
           is = u.openStream();
           dis = new DataInputStream(new BufferedInputStream(is));
           while ((s = dis.readLine()) != null) {
        } finally {

All the credits to Alexander.
