CS 222 Spring 2016

Simple Note Taker, Part III

Due: March 03, Thursday, 11:00 am.

Language: Java

Submission:

• Your file containing the main method WILL HAVE the name NoteCat.java
• DO NOT include package names
• Check your file encoding. It should be UTF-8
• Commit your code to SVN

Task 1

Add two new commands to your CLI: list and rename

1. list command takes a note name as an argument or “all” to list all the notes.
   • When user enters “list all”, names of all notes taken is printed on the screen.
2. rename command takes a note name as an argument, it renames this note.
   • Ask the user for a new name for renaming.
3. Expand your help menu with these new commands.

Task 2

Print error messages on the screen for these commands. Apart from error commands you are required to:

1. For list command:
   • Warning message: Print something like “You don’t have any notes yet” when “list all” command cannot find any notes.
2. For rename command:
   • Warning message: After you read the command “rename note”, ask for the new note name. Note name cannot contain space character, any other character (unless it’s turkish) is allowed. Warn the user with a message like “Invalid note name for renaming. It contains ‘ ‘.” if it contains spaces. Until a decent name for renaming is supplied, keep asking the user.
   • Also user cannot rename a note if a note with the new name already exists on the system. (See the last example where I try to rename scarlet to pink in the run given below)

See the example given below for Task 1 and Task 2. Make sure that you cover all errors and warnings listed here.
