Instance Variable/ 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 paid
Member methods:
1) Void accept() – to accept the name of the customer and number of units consumed
2) Void calculate() – to calculate the bill as per the following tariff :
| Number of units | Rate per unit |
| First 100 units | Rs.2.00 |
| Next 200 units | Rs.3.00 |
| Above 300 units | Rs.5.00 |
A surcharge of 2.5% charged if the number of units consumed is above 300 units.
3) Void print() – To print the details as follows :
Name of the customer ………
Number of units consumed ……
Bill amount …….
Write a main method to create an object of the class and call the above member methods.
import java.util.Scanner;
class ElectricityBill
{
String n;
int units;
double bill;
void accept()
{
Scanner in = new Scanner(System.in);
System.out.println("Enter the name of the customer");
n = in.nextLine();
System.out.println("Enter the number of units consumed");
units = in.nextInt();
}
void calculate()
{
if(units<=100)
bill = 2*units;
else if(units>100 && units<=300) //next 200 units
bill = 2*100 + (units-100)*3;
else if(units>300)//above 300 units
{
bill = 2*100 + 3*200 + (units-300)*5;
bill = bill + 2.5*bill/100; //surcharge 2.5%
}
}
void print()
{
System.out.println("Name of the customer : " + n);
System.out.println("Number of units consumed : " + units);
System.out.println("Bill Amount: " + bill);
}
public static void main(String args[])
{
ElectricityBill obj = new ElectricityBill();
obj.accept();
obj.calculate();
obj.print();
}
}
