You will add features to a program that have written that works with weather data provided by the Climate Data Online service of the National Oceanic and Atmospheric Administration. The program in its current form will read data from any of the three files below and display the information in a GUI. However, it doesn't display all the information that is provided in the files for Berlin, Ohio and the Akron-Canton Airport. There are also several buttons that currently don't work. You are supposed to fill in the missing functionality.

Data files:

Berlin, Ohio Akron-Canton Airport (CAK) Chardon, Ohio Documentation on the format of the data can be read here. To test the program on these files, you should download each file to your computer; when you run the program and press the Read from file button, a dialog box will pop up and you can browse to find the file. Here is a task list to follow to help guide:

Add code to sort the objects in weatherRecordList by date; each click on the associated button should reverse the sort order from the previous time the data was sorted by date Add code to sort the objects in weatherRecordList by precipitation; each click on the associated button should reverse the sort order from the previous time the data was sorted by precipitation Add code to clear all the objects out of weatherRecordList (hint: just replace the current list with a new empty one)

Please try to keep it simple, and please explain how it works. Thank you
