Lab: Experimenting with Input/Output



3.3. What was the first error generated by the compiler?

It could not find the class PrintWriter.


3.4. What line did you need to add?

"import java.io.*;"


3.6. What was the first error generated by the compiler this time?

It could not find the Scanner class.

3.7.  Fix this error.  What line did you need to add?

"import java.util.*;"

4.4. Why was no output generated?

Because the buffer wasn't flushed.

4.5. Fix this mistake.  What line did you add?

"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?

One should be able to type in anything that isn't a double.

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?

The terminal gave the output "bash: anniversarys.txt: No such file or directory", because there is not a file with the name "anniversarys.txt" in my L10-02 folder.

5.8 What changes did you need to make?

Had to add the line "File                     dates;".  The only reason for the spacing is so it matches GregorianCalendar today and String name.
