Define a class ElectricBill() with the following descriptions: Class - ElectricBill , Instance varaibles : 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: First 100 units - rate per unit = rs. 2.00, Next 200 units - rate per unit = rs. 3.00; Above 300 units - rate per unit = 5.00.A surcharge of 2.5 % charged if the number of units is above 300 units. Write a main() method to create an object of the class and call the above member methods.

 THE FOLLOWING PROGRAM SEGMENT SHOWS HOW TO DO THE ABOVE OPERATIONS:

import java.util.*;

class ElectricBill

{

    String s;

        int units;

        double bill;double surcharge = 0.0;

    void accept()

    {

    Scanner ob = new Scanner (System.in);

    System.out.println("Enter the name of the customer");

    s = ob.nextLine();

     System.out.println("Enter the number of units consumed");

     units = ob.nextInt(); 

    }

    void calculate()

    {

        if(units<= 100)

        {

            bill = units*2.00;

        }

         if(units <= 300)

        {

            bill = units*3.00;

        }

        if(units > 300)

        {

            bill = units * 5.00;

            surcharge = (2.5/100)*bill;

        }

    }

    void print()

    {

         System.out.println("Name of the customer " + s );

          System.out.println("Number of units consumed " + units);

           System.out.println("The bill amount = " + bill);

           System.out.println("surcharge is = "+surcharge);

        }

        public static void main (String args[])

        {

            ElectricBill obj = new ElectricBill();

            obj.accept();

            obj.calculate();

            obj.print();

        }

    }

The above program is compiled and is without any error.
