Question

Define a class ElectricBill with the following specifications :

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.

Answer 1

import java.io.*;
class ElectricBill {
String n;
int units;
double bill ;
void accept() throws IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
System.out.print(“Name of the customer = “);
n = reader.readLine( );
System.out.print( “Number of units consumed = “);
String un = reader. readLine( );
units=Integer .parselnt(un);
}
void calculate!) {
if(units < = 100)
bill = 2.00*units;
if(units< =300) bill = 3.00*units; if (units > 300)
bill = 5.00*units;
}
void print( ) {
System.out.println(“Naine of the customer:” +n);
System.out.println(“Number of units consumed:” +units);
System.out.println(“Bill amount:” + bill);
}
public static void main(String argsQ) throws IO
Exception { ElectricBill eb = new ElectricBill( );
eb. accept!);
eb.calculate();
}
}
