Need help with Java File input and file output program

[Kdiddle88]

I need to create a program that uses a MathInput.cvs file. It needs to take the data in this file and calculate and send the results to the output file MathOutput.csv .
The results should be something like this for the first set in the output file "MathOutput.csv".* Notice that the format included the name of the operation. followed by the number, then the word Total", *followed by the result of the operation.* At the end of a set of operations, your program should include a summary line with the text "Number of elements = ", then the actual number of elements, followed by the text "Total = ", followed by the calculated total of the operations, followed by the text "Average = " followed by the calculated average.* Between each set of output, display a line of *. See the example below:
Add * ******* 2* *** Total* ******* 2
Add** ******* 6 **** Total **** *** 8
Subtract** * 9* *** Total **** ** -1
Multiply* * 10 **** Total* ****** -10
Number of elements = 4, Total = -10, Average = -2.5
********************************************
Divide******* 4***** Total* 0
Multiply***** 5***** Total 0
Subtract**** 6***** Total -6
Number of elements=3, Total = -6, Average = -2
