How can I read image from URL in Java?

URL url = new URL("http://www.digitalphotoartistry.com/rose1.jpg");
Image image = ImageIO.read(url);  

or

URL url = new URL("http://www.digitalphotoartistry.com/rose1.jpg");
java.awt.Image image = java.awt.Toolkit.getDefaultToolkit().createImage(url);   

Update:

This code works for me Try checking your URL.

public static void main(String[] args) throws Exception {
   URL imageURL = new URL("http://www.digitalphotoartistry.com/rose1.jpg");
    // Case 1
    RenderedImage img = ImageIO.read(imageURL);
    System.out.println(img);
}

output:

BufferedImage@e80a59: type = 5 ColorModel: #pixelBits = 24 numComponents = 3 col
or space = java.awt.color.ICC_ColorSpace@1ff5ea7 transparency = 1 has alpha = fa
