5.6. What happened and why?
bash: anniversarys.txt: No such file or directory 
This happened because the file does not exist in our working directory
          

5.8 What changes did you need to make?
add File dates;
          

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


5.12. What changes did you need to make?
 try
		 {
		 	dateScanner = new Scanner(dates);
		 }
		 catch(FileNotFoundException e)
		 {
		 	System.err.println("No File");
		 }

          
5.14. What output was generated?

6.2. What changes did you need to make?
wrap around the dateScanner and processDate statement: for(int i = 0; i < args.length; i++)
and move dates 	 = new File(args[i]); inside the loop
