Hi
You can use below code for re-size and uploading.

import java.awt.Graphics2D;
import java.awt.Image;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.awt.image.DataBufferByte;
import java.awt.image.WritableRaster;

public class ImageUpload1  {
 
    private static final int IMG_WIDTH = 120;
    private static final int IMG_HEIGHT = 120;

    ImageIcon photo;
    WritableRaster raster;
    DataBufferByte data;
    File image;
 
                         
 
     void reSize() {                                         
         try {
               image = new File("image path");
                BufferedImage originalImage = ImageIO.read(image);
                int type = originalImage.getType() == 0 ? BufferedImage.TYPE_INT_ARGB : originalImage.getType();
 
                BufferedImage resizeImageJpg = resizeImage(originalImage, type);
                photo = new ImageIcon(toImage(resizeImageJpg));
 
                //converting buffered image to byte array
                raster = resizeImageJpg.getRaster();
                data = (DataBufferByte) raster.getDataBuffer();
               Save();
            } catch (IOException e) {
                System.out.println(e.getMessage());
            }
          
    }

                    + "values(?)");

            psmnt.setBytes(1, extractBytes);
            // executeUpdate() method execute specified sql query. Here this query 
            //insert data and image from specified address. 
            int s = psmnt.executeUpdate();
            if (s > 0) {
                System.out.println("Uploaded successfully !"); 
             
            } else {
                System.out.println("unsucessfull to upload image.");
            }
            connection.close();
            psmnt.close();
        } // catch if found any exception during rum time.
