Write a Java^TM GUI application using NetBeans^TM Integrated Development Environment (IDE) that does home utility auditing.

The user should be able to:

• Enter the cost per kilowatt-hour.
• Select from a list of 5- to 7-home appliances which includes a washer, among other appliances.
• Enter the power needed in kilowatts (kW) for the selected appliance.
• Enter the number of hours used per day for the selected appliance.
• If the washer is selected, enter both the number of gallons of water used by the washer per hour and the cost per gallon.

The program should:

• Validate that the data entered has the correct format, and is within a reasonable range.
• Calculate and display the cost for operating a home appliance as soon as the data is entered.
• Create a listing area to display each of the following for each appliance entered:
  • Home Appliance
  • Number of hours per day
  • Cost
  • Display and update the total cost of all appliances, as soon as a new entry is added to the listing area.

The Java^TM application should meet these technical requirements:

• The application should have at least one class, in addition to the application's controlling class (a controlling class is where the main function resides).
• There should be proper documentation in the source code.
