First Creat Product Class
Start Product Class

public class Product {
    
    private int id;
    private String name;
    private float price;
    private String addDate; 
    private byte[] picture;
    
    public Product(int pid, String pname, float pprice, String pAddDate, byte[] pimg)
    {
        this.id = pid;
        this.name = pname;
        this.price = pprice;
        this.addDate = pAddDate;
        this.picture = pimg;
    }
    
    public int getId()
    {
        return id;
