URL to a File.

Question

I'm trying to save a website in a HTML file with Java.
I tried this:
url = new URL("http://www.google.com");
URI uri = url.toURI();
File f = new File(uri);
f.createNewFile();
But it doesn't work. It says: URI scheme is not "file"
Is there a way to convert a website (example: http://www.google.com) to a HTML file.
Or is there a way to convert the HTML code of a website in a variable in Java? I know it's possible to do a new BufferedReader(new FileReader("file.html")), but is it possible directly from a website?

I tried this:
url = new URL("http://www.google.com");
URI uri = url.toURI();
File f = new File(uri);
f.createNewFile();That's not the same thing as what you said you wanted to do.
The URL you created pointed to Google's home page. When you create a File object based on that URL, it's like trying to overwrite their home page. It doesn't copy the results of the URL to the file.
Read the API docs for details.
But it doesn't work. It says: URI scheme is not
"file"Yeah, apparently that method only lets you write to local files. it won't let you, for example, write a file on www.google.com.

http://www.google.com) to a HTML file.
Do you want to create a website or a web page? Presumably the latter.
Or is there a way to convert the HTML code of a
website in a variable in Java? I know it's possible
to do a new BufferedReader(new
FileReader("file.html")), but is it possible directly
from a website?Yeah, from the URL, get the content with, if I recall correctly, "getContent". Then write that result to a file.
It's late at night, I have insomnia, let's try it out....
import java.net.*;
import java.io.*;
public class TestGoogle {
  public static void main(String[] argv) {
    try {
      URL u = new URL(argv[0]);
      InputStream content = (InputStream) u.getContent();
      BufferedReader in = new BufferedReader(new InputStreamReader(content));
      String line;
      PrintWriter out = new PrintWriter(new FileWriter("TestGoogle.txt"));
      while((line = in.readLine()) != null) {
     out.println(line);
      out.close();
    } catch (IOException e) {
      e.printStackTrace();
}That works for the Google home page, although when I pass a search it returns 403. This may be a deliberate decision on Google's part to restrict serving content to bots, which would be ironic. Or maybe I just missed something. Anyway it demonstrates how to use a URL to get content and write it to a file.
