URL
Read text from URL
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()); } } }
This was an example of how to parse text from a URL in Java.
