ICSE Java Programming Electricity Bill  2017 Q4  Solved

Question 4.

Define a class Electricity Bill with the following specifications : [15]
class : ElectricBill
Instance variables /data member :
String n – to store the name of the customer
int units – to store the number of units consumed
double bill – to store the amount to be paid
Member methods :
void accept ( ) – to accept the name of the customer and number of units consumed
void calculate ( ) – to calculate the bill as per the following tariff :

A surcharge of 2.5% charged if the number of units consumed is above 300 units.

Write a main method to create an object of the class and call the above member methods.

Python Code

class ElectricityBill:

    def accept(self):

        self.customer_Name = str(input("Enter the name of the customer:"))

        self.units_Consumed = int(input("Enter the units consumed:"))

    def calculate(self):

        if self.units_Consumed <= 100:

            self.bill_Amount = self.units_Consumed *2.0

        elif self.units_Consumed > 100 and self.units_Consumed <= 300:

            self.bill_Amount  = self.units_Consumed *3.0

        else:

            self.bill_Amount  = self.units_Consumed *5.0

self.bill_Amount  += self.bill_Amount*(2.5/100.0)

    def printBill(self):

        print("Name of the customer: ",self.customer_Name)

        print("Total units consumed: ",self.units_Consumed)

        print("Bill Amount: ",self.bill_Amount)

    def __init__(self) -> None:

        self.customer_Name = ""

        self.units_Consumed = 0

        self.bill_Amount =0.0

obj = ElectricityBill()
