Need to below added to my java program already written

I am willing to pay $10.00 for the below.  I have the program already, just need this added and need it within a couple hours.

Update the Java™ GUI application in week Three using NetBeans™ Integrated Development Environment (IDE) that does home utility auditing.

The user should be able to:

• Export the data in the listing area to an external text file.
• Change default power ratings of a selected appliance.

The program should:

• Use arrays or ArrayList where applicable.
• Read the default power rating for appliances from an external text file.
