Can i save a screenshot taken from netbeans to Mysql

I am doing a project in which i decided to save screenshot of the bill to mysql database. But the ImageIcon used to take the screenshot does not provide the length of file so, the setBinaryStream() isn't working, i have tried pstmt.setBlob (1, (BLOB)icon), still not working.

Can you save the taken screenshot directly to database, if so please tell me.
Or can i create and save custom bills in netbeans.

try
{
    Rectangle screen = new Rectangle (Toolkit.getDefaultToolkit().getScreenSize());
    BufferedImage capture = new Robot().createScreenCapture(screen);
    ImageIcon icon = new ImageIcon(capture);
    int len = icon.getWidth();
    ImageIO.write(capture,"jpg",new File("screenshot.jpg"));
    
        try {
            Class.forName("com.mysql.jdbc.Driver");
        } catch (ClassNotFoundException ex) {
            Logger.getLogger(Sign_up.class.getName()).log(Level.SEVERE, null, ex);
        }
        try (Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/webapp","root","")) {
            Statement at = con.createStatement();
            String qt = "insert into picture (Pictures) values (?)";
            PreparedStatement pstmt = con.prepareStatement(qt);
            pstmt.setBinaryStream (icon,);
    
}

You can create a ByteArrayInputStream using the bytes of the screenshot, and then pass it to the prepared statement using setBinaryStream(int,InputStream) like this...

ps.setBinaryStream (1,new ByteArrayInputStream(baos.toByteArray()));

Here is a full program that takes a screenshot, writes it to a BLOB, and then reads it from the BLOB, and writes it to a file (for verification).

import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import javax.imageio.ImageIO;
public class ScreenShot {
public static void main(String[] args) throws Exception {
if (args.length != 3) {
// Note: Don't pass passwords on the command line in real life.
System.err.println("Usage: java ScreenShot <dbUrl> <dbUser> <dbPwd>");
return;
}
// Capture the screenshot
Rectangle screen = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
BufferedImage capture = new Robot().createScreenCapture(screen);
// Write it to a ByteArrayOutputStream
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(capture, "jpg", baos);
// Insert the bytes into the database
Connection connection = DriverManager.getConnection(args[0], args[1], args[2]);
String sql =  "insert into picture (Pictures) values (?)";
PreparedStatement ps = connection.prepareStatement(sql);
ps.setBinaryStream (1,new ByteArrayInputStream(baos.toByteArray()));
ps.execute();
// Select the image from the database.
sql = "select Pictures from picture where id = 1";
ps = connection.prepareStatement(sql);
ResultSet rs = ps.executeQuery(sql);
if (rs.next()) {
InputStream input = rs.getBinaryStream(1);
// Write the image to a file (for verification).
FileOutputStream fos = new FileOutputStream("screenshot.jpg");
byte[] buffer = new byte[1024];
while (input.read(buffer) > 0) {
fos.write(buffer);
}
input.close();
fos.close();
}
}
}

Note, this requires a table like below to exist in the default schema connected to.

CREATE TABLE test.picture (
id int AUTO_INCREMENT ,
Pictures MEDIUMBLOB,
PRIMARY KEY (id)
);

Maybe instead of saving the image data directly to the database (not recommended) save the file somewhere (like a remote file hosting service). Then in the SQL statement save the link of the file.
