how to download image from any web page in java

Question

hi I am trying to download image from web page. I am trying to download the image from 'http://www.yahoo.com' home page. Please tell me how to pass 'http://www.yahoo.com' as a input. And on opening this web page how to fetch image from this page. Please give me java code to fetch the image from web page.

Answer 1

try (URL url = new URL("http://www.yahoo.com/image_to_read.jpg")) {     Image image = ImageIO.read(url); } catch (IOException e) {     // handle IOException } 

See javax.imageio package for more info. That's using the AWT image. Otherwise you could do:

URL url = new URL("http://www.yahoo.com/image_to_read.jpg"); InputStream in = new BufferedInputStream(url.openStream()); ByteArrayOutputStream out = new ByteArrayOutputStream(); byte[] buf = new byte[1024]; int n = 0; while (-1!=(n=in.read(buf))) {    out.write(buf, 0, n); } out.close(); in.close(); byte[] response = out.toByteArray(); 

And you may then want to save the image so do:

FileOutputStream fos = new FileOutputStream("C://borrowed_image.jpg"); fos.write(response); fos.close();
