I need help with this Java exercise.

Dr. Harrison keeps student scores in an Excel file. This can be exported as a comma separated text file. Each students data will be on one line. We want to write a Java program that will find the average for each student. (The number of students changes each year.)

Modify the source code included to do the following:

Source code link for (TestScoreReader): http://www.jade-cheng.com/hpu/2012-spring/csci-2912/text-processing-and-wrapper-classes-ii/TestScoreReader.java.

(TestAverages) source code: http://www.jade-cheng.com/hpu/2012-spring/csci-2912/text-processing-and-wrapper-classes-ii/TestAverages.java?

Instead of reading the data from the Excel spreadsheet, Create a database called Classes and a table called Grades with the fields and data as specified in the Excel attached.
