Hi Friend,

Try the following code:

import java.util.*;
class Product{
    int productID;
    String name;
    int categoryID;
    double price;
    Product(int productID,String name,int categoryID,double price){
        this.productID=productID;
        this.name=name;
        this.categoryID=categoryID;
        this.price=price;
    }
}
    public class ElectricalProduct extends Product{
        int voltageRange;
        int wattage;
        ElectricalProduct(int productID,String name,int categoryID,double price,int voltageRange, int wattage){
        super(productID,name,categoryID,price);
        this.voltageRange=voltageRange;
        this.wattage=wattage;
        }
        public void display(){
            System.out.println("Product ID: "+productID);
            System.out.println("Name: "+name);
            System.out.println("Category ID: "+categoryID);
            System.out.println("Price: "+price);
            System.out.println("Voltage Range: "+voltageRange);
            System.out.println("Wattage: "+wattage);
        }
    public static void main(String[] args) 
    {
        Scanner input=new Scanner(System.in);
        System.out.println("Enter Product ID: ");
        int pid=input.nextInt();
        System.out.println("Enter Name: ");
        String name=input.next();
        System.out.println("Enter Catagory ID: ");
        int cid=input.nextInt();
        System.out.println("Enter Price: ");
        double price=input.nextDouble();
        System.out.println("Enter Voltage Range: ");
        int vrange=input.nextInt();
        System.out.println("Enter Wattage: ");
        int wattage=input.nextInt();
        System.out.println("****Details of Electrical Product****");
        System.out.println();
        ElectricalProduct p=new ElectricalProduct(pid,name,cid,price,vrange,wattage);
        p.display();
    }
}

Thanks
