The following code downloads an image from a direct link to the disk into the project directory  Also note that it uses try-with-resources   import java io BufferedInputStream  import java io BufferedOutputStream  import java io File  import java io FileNotFoundException  import java io FileOutputStream  import java io IOException  import java io InputStream  import java io OutputStream  import java net MalformedURLException  import java net URL   import org apache commons io FilenameUtils   public class ImageDownloader       public static void main String   arguments  throws IOException               downloadImage  https   upload wikimedia org wikipedia commons 7 73 Lion waiting in Namibia jpg                   new File     getAbsolutePath                public static void downloadImage String sourceUrl  String targetDirectory              throws MalformedURLException  IOException  FileNotFoundException               URL imageUrl   new URL sourceUrl           try  InputStream imageReader   new BufferedInputStream                  imageUrl openStream                     OutputStream imageWriter   new BufferedOutputStream                          new FileOutputStream targetDirectory   File separator                                   FilenameUtils getName sourceUrl                            int readByte               while   readByte   imageReader read       -1                                imageWriter write readByte

throws IOException   Image image   null  try       URL url   new URL  http   www yahoo com image to read jpg        image   ImageIO read url     catch  IOException e        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
