File I/O Exception
Algorithm:
Any exceptions related file I/O are checked exceptions.
It is required to handle them.
Make sure add throws IOException clause in the main method signature
then create a Scanner object and associate it with the File object
Create a FileWriter object and associate it with the output file and
then create a PrintWriter object and associate it with the FileWriter object
Read the first line (caption) and discard it
Use a while to check the end of file indicator (as long as the file has data item):
Read data items one at a time
Calculate the new salary
Add current salary to total salary
Add new salary to total new salary
Increment count by 1
Remove _ from the name
Save the individual data items to output file
Once the loop is ended, calculate the averages and save them to the output file.
Close both file input and output objects
