Lab: Experimenting with Input/Output



3.3. What was the first error generated by the compiler?
Rooter.java:8: cannot find symbol,
It could not identify the PrintWriter object


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?
Rooter.java:10: cannot find symbol,
The Scanner class wasn't imported


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


4.4. Why was no output generated?
The output is stuck in the buffer memory, so the file is sitting and waiting for the output.


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?
The only way to exit out of the program (currently) is Ctrl + Z.  The while (keyboard.hasNext()) will always loop because there is always a next currently.  A better way to do this would be to set it so that if the input's length is equal to 0, end the program.


5.4. What output was generated?
