Can you please modify the following program so that it does two things:

1) Modify so that it can be directed to an output file. Note: PrintWriter object has already been created its called "outputFile". User prompts do not need to be directed to an output file.

Sample output:

Operation: addition

augend: 25

addend: 35

sum: 60

2) Call a separate Method for each operation. In the code below under the comment that reads //Case for arithmetic operations and their respective methods. I wrote a case for each operation. I have highlighted the cases in bold so that you know which ones to change to methods instead. I would like to change that and call a separate method for each operation.

THANK YOU!!
