I think this is what you need.
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.URL;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.imageio.ImageIO;
public class ReadImages {
public static void main(String[] args) {
try {
BufferedImage img = ImageIO.read(new URL("https://t.williamgates.net/image-E026_55A0B5BB.jpg").openStream());
ImageIO.write(img, "jpg", new File("image.jpg"));
} catch (IOException ex) {
Logger.getLogger(ReadImages.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
You should include the following classes

Try this for any files, not just images:
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.MalformedURLException;
import java.net.URL;
public class DownloadFiles {
public static void main(String[] args) throws MalformedURLException, IOException {
InputStream in = new BufferedInputStream(new URL("https://t.williamgates.net/image-E026_55A0B5BB.jpg").openStream());
OutputStream out = new BufferedOutputStream(new FileOutputStream(new File("img.jpg")));
int data;
while((data = in.read()) != -1){
out.write(data);
}
in.close();
out.close();
}
}
You can make it faster when you use the in.read (byte b [], int off, int len) method instead of in.read (). Just go to Google for some examples.
