Cannot find Symbol for class PrintWriter;


3.4. What line did you need to add?
import java.io.PrintWriter;


3.6. What was the first error generated by the compiler this time?
Cannot find Symbol for class Scanner


3.7.  Fix this error.  What line did you need to add?
import java.util.Scanner;


4.4. Why was no output generated?
Because the string was in the buffer and in order to output
the string the buffer needs to be flushed.

screen.flush();


4.6. What do you need to type in the terminal window (as a response to
the prompt) in order to make this application terminate normally?
Ctrl+Z


5.4. What output was generated?
Today's Date: 22 January 2007
	Birthday: Sir Francis Bacon
	Birthday: George Foreman


5.6. What happened and why?
It outputted "The system cannot find the file specified" because there was no
anniversarys.txt in the directory.
          

5.8 What changes did you need to make?
Added File dates; to the program.
          

5.10. What changes did you need to make?
Added dates = new File(args[0]);

Changed dateScanner = new Scanner(System.in); to dateScanner = new Scanner(dates);
Added a try,catch in order to catch a FileNotFoundException

6.2. What changes did you need to make?
Made dates an array.
Added a for loop in order to catch all the command line arguments from index = 0 to index < args.length, and creating a new File object for each argument. Also, instantiating dateScanner with each new File object.

          
6.4. What output was generated?
