How to fetch HTML in Java

Question

Without the use of any external library, what is the simplest way to fetch a website's HTML content into a String?

Answer 1

I'm currently using this:

String content = null; URLConnection connection = null; try {   connection =  new URL("http://www.google.com").openConnection();   Scanner scanner = new Scanner(connection.getInputStream());   scanner.useDelimiter("\\Z");   content = scanner.next();   scanner.close(); }catch ( Exception ex ) {     ex.printStackTrace(); } System.out.println(content); 

But not sure if there's a better way.

Answer 2

This has worked well for me:

URL url = new URL(theURL); InputStream is = url.openStream(); int ptr = 0; StringBuffer buffer = new StringBuffer(); while ((ptr = is.read()) != -1) {     buffer.append((char)ptr); } 

Not sure at to whether the other solution(s) provided are any more efficient or not.
