How to connect to a URL and read its content in Java?

You can read content of an URL object aftter connecting to it. You have to call the URL's openStream() method to get a stream from which you can read the contents of the URL. The openStream() method returns a java.io.InputStream object, so reading from a URL is as easy as reading from an input stream. Below example shows sample code:

package com.myjava.url;

import java.io.IOException;
import java.io.InputStream;
import java.net.MalformedURLException;
import java.net.URL;

public class MyUrlContentRead {

    public static void main(String a[]){
    
        URL url = null;
        InputStream is = null;
        try {
            url = new URL("http://www.java2novice.com");
            is = url.openStream();
            byte[] b = new byte[8];
            while(is.read(b) != -1){
                System.out.print(new String(b));
            }
        }  catch (MalformedURLException ex) {
            ex.printStackTrace();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
}
