how to download image from any web page in java

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();

If you want to save the image and you know its URL you can do this:

try(InputStream in = new URL("http://example.com/image.jpg").openStream()){    Files.copy(in, Paths.get("C:/File/To/Save/To/image.jpg"));}

You will also need to handle the IOExceptions which may be thrown.

   // Do you want to download an image?   // But are u denied access?   // well here is the solution.    public static void DownloadImage(String search, String path) {    // This will get input data from the server    InputStream inputStream = null;    // This will read the data from the server;    OutputStream outputStream = null;    try {        // This will open a socket from client to server        URL url = new URL(search);       // This user agent is for if the server wants real humans to visit        String USER_AGENT = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36";       // This socket type will allow to set user_agent        URLConnection con = url.openConnection();        // Setting the user agent        con.setRequestProperty("User-Agent", USER_AGENT);        // Requesting input data from server        inputStream = con.getInputStream();        // Open local file writer        outputStream = new FileOutputStream(path);        // Limiting byte written to file per loop        byte[] buffer = new byte[2048];        // Increments file size        int length;        // Looping until server finishes        while ((length = inputStream.read(buffer)) != -1) {            // Writing data            outputStream.write(buffer, 0, length);        }    } catch (Exception ex) {        Logger.getLogger(WebCrawler.class.getName()).log(Level.SEVERE, null, ex);     }     // closing used resources     // The computer will not be able to use the image     // This is a must     outputStream.close();     inputStream.close();}
