Image to ByteArray to BLOB and BLOB to ByteArray to Image Conversion Issues in Java

After a lot of learning on ByteArrays & BLOBS, I managed to write the below Java code to write an image into Access DB (Using ucanaccess) and writing it back to Disk.

When I write an image back to disk the image is in incorrect format or something is messed up that you cannot open that image.

I understand it is not a good practice to store Images on DB but, this is only for my learning.

public static void Update_to_DB() throws SQLException, IOException {
    String URL = "jdbc:ucanaccess://C:\\Users\\bharat.nanwani\\Desktop\\Images.accdb";
    Connection conn = DriverManager.getConnection(URL);
    //Statement stmt = conn.createStatement();
    PreparedStatement p;

    File ImgPath = new File("C:\\Users\\bharat.nanwani\\Desktop\\Desert.jpg");
    BufferedImage bufferedimage = ImageIO.read(ImgPath);

    WritableRaster raster = bufferedimage.getRaster();
    DataBufferByte data = (DataBufferByte) raster.getDataBuffer();

    byte[] bytearray = date.getdata();


    String query = "INSERT INTO Images(data) VALUES(?);";
    p = conn.prepareStatement(query);
    p.setBinaryStream(1, new ByteArrayInputStream(bytearray),bytearray.length);
    p.execute();
}

public static void update_to_DISK() throws SQLException, IOException {
        String URL = "jdbc:ucanaccess://C:\\Users\\bharat.nanwani\\Desktop\\Images.accdb";
        Connection conn = DriverManager.getConnection(URL);
        PreparedStatement p;
        ResultSet rs;
        String query = "SELECT Data FROM Images";
                p=conn.prepareStatement(query);
        rs = p.executeQuery();
        if (rs.next()) {
        Blob blob = rs.getBlob("Data");

        byte[] bytearray = blob.getBytes(1L, (int)blob.length());

        FileOutputStream fos = new FileOutputStream("C:\\Users\\bharat.nanwani\\Desktop\\New Folder\\test.jpg");
        fos.write(bytearray);
        fos.close();

        System.out.println(bytearray);
        } 
    }
