ques - Create Product having following attributes: Product ID, Name, Category ID and UnitPrice. Create ElectricalProduct having the
following additional attributes: VoltageRange and Wattage. Add a behavior to change the Wattage and price of the electrical
product. Display the updated ElectricalProduct details.

import java.io.*;
class Product
{
int productId;
String productName;

double unitPrice;
Product(double a)
{
unitPrice = a;
