Java program to calculate Electricity Bill

Steps:

1.Import java.util.*;

2.Add class with public static void main method

3. Declare all variables with their respective datatypes 

4. Declare object of Scanner

            Scanner sc= new Scanner(System.in);

5.Take input from user in following way:

            a.Customer Name (String)

            b.Customer Id (Int)

            c.Month in the from MMM-YYYY(String)

            d.Previous month meter reading(Int)

            e.Current month meter reading(Int)

6.Calculate unit consumed using previous month meter reading and currrent month meter reading 

                     unitConsumed = currentReading - previousReading 

7.Calculate Energy charges using following information

       Unit Consumed          0-100     101-300     301-500     501-1000     >1000

       Rate (per unit)           3.44       7.34           10.36         11.82           11.82

8.Fixed charges are also added for each month as per electricity board.

    Note: charges may vary state to state or after certain time period

9.Wheeling charges are applied 1.38 Rs per unit consumed 

         wheelingCharges = 1.38 * unitConsumed;   

10.Electricity duty charges are applied 16% on sum of energy charges , charges and wheeling charges

11.Calculate the total bill by taking sum of all charges 

12.Printing all values

Output:
