How to get the content of a webpage in Java?

Question

Java

I want to get the content of a web page from a specific resource, for example, yandex.ru
Here's the code:

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.*;
public class pageFromSite {
 
    public static void main(String[] args) throws Exception {
        URL url = new URL("http://yandex.ru/");
        BufferedReader reader = new BufferedReader(new InputStreamReader(url.openConnection().getInputStream(), "UTF-8"));
        while (true) {
            String line = reader.readLine();
            if (line == null)
                break;
            System.out.println(line);
        }
    }
}

Compiles successfully, but after running it throws an error:
