• Customer class
  • Attributes
    • firstName: String type, initial value null
    • lastName: String type, initial value null
    • streetAddress: String type, initial value null
    • city: String type, initial value null
    • state: String type, initial value null
    • zip: String type, initial value null

    • setCurrentMeterReading(int reading): void method
    • calculateGallonsUsed(): void method
    • calculateBill(): void method
    • toString(): String
    • getX/setX methods for all attributes listed above

More Info:

1. When a customer is created some validation of information mustoccur:
   1. The state is a 2 character abbreviation, the value suppliedmust be exactly 2 characters in length
   2. The zip code must be 5 characters in length
   3. The value for previousMeterReading must be >= 0
   4. These rules must also be enforced in the “setters” provided forthese values as well as in the constructor.
   5. If a condition is invalidated throw an exception in theform

if (previousMeterReading < 0)

            thrownew RuntimeException(“The value for the previous meter reading is “+  “ invalid, it must be greater than or equal tozero”);

1. method setCurrentMeterReading:  Thismethod sets the value for the data member“currentMeterReading”, if the value is<0  OR less than thepreviousMeterReadingfor the customer, an exceptionshould be thrown.  If a valid value is input, call theprivate method “calculateGallonsUsed” to set thegallonsUseddata member to the difference betweenthe previous meter reading the current meter reading.
2. toString():  prints out all of thecustomer information ,  (all data members), along withthe amount of the current bill. Be sure to format the informationso that it is clear to read, and well organized.
3. calculateBill:  This method computesa customer’s current bill based on the gallons used in the currentmonth and stores the result into the“currentCharges” data member.  Acustomers charges are calculated according to the followingrules:

Rate Schedule

gallons/month

rate

first 5,000

$10.90 per 1,000 gallons

next 5, 000

$10.55 per 1,000 gallons

next 10,000

$10.00 per 1, 000 gallons

next 10,000

$9.45 per 1,000 gallons

all Over 30,000

$8.60 per 1,000 gallons

The minimum customer bill is $31.54

Use String.format OR printf so that the bill isdisplayed correctly as dollars and cents with  2 decimalplaces.
