This is an example of how to parse text from a URL. The URL Class is used to represent a Uniform Resource Locator, a pointer to a “resource” on the World Wide Web. Parsing text from a URL implies that you should:

Create a URL object from the String representation.
Use openStream() API method to open a connection to this URL and and get the InputStream for reading from that connection.
Create a new BufferedReader, using a new InputStreamReader with the URL input stream.
Read the text, using readLine() API method of BufferedReader.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;
 
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
 
public class ReadTextFromURL {
     
    public static void main(String[] args) {
         
        try {
             
            URL url = new URL("http://www.google.com:80/");
             
            // read text returned by server
            BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
             
            String line;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
            in.close();
             
        }
        catch (MalformedURLException e) {
            System.out.println("Malformed URL: " + e.getMessage());
        }
        catch (IOException e) {
            System.out.println("I/O Error: " + e.getMessage());
        }
         
    }
 
}
