Question

The electric company charges according to the following rate schedule:

9 cents per kilowatt-hour (kwh) for the first 300 kwh
8 cents per kwh for the next 300 kwh (up to 600 kwh)
6 cents per kwh for the next 400 kwh (up to 1000 kwh)
5 cents per kwh for all electricity used over 1000 kwh

Write a program that would repeatedly read in a customer number (an integer) and the usage for that customer in kwh (an integer). The program should include a method to compute the total charge for each customer. Use the following template for the method:

// takes kwh and calculates the total charge for that customer.

public static double findCharge(int kwh){

        // put your code here

}

The program should terminate when the user enters a sentinel value of -999 for the customer number. The program should print a three-column chart listing the customer number, the kilowatt-hours used, and the total charge for each customer. The program should also compute and print the number of customers, the total kilowatt-hours used, and the total charges. Use a JTextArea component within a JOptionPane dialog box to display the output. Should not use arrays for this program.
