IB Computer Science 2

Friday (9/24/10)

Warmup:

• You will be creating a user interface menu for use with your AddressBook
• Open / create your AddressBook's main method
• Inside the main method, create an AddressBook variable:

AddressBook book = new AddressBook();

• Print out a message that explains the program (e.g. "Welcome to YOUR_NAME's address book!")
• Print out a menu with the following options:

(a)dd to address book
(p)rint address book
(q)uit

What would you like to do? 

• You should prompt for input after the menu is printed. Review Media:JavaIOExample.java for examples of input/output
  1. Add import java.io.*; at the very top
  2. Add private static BufferedReader stdin = new BufferedReader( new InputStreamReader( System.in ) ); before main()
  3. Add throws IOException so that main() reads like public static void main(String [] args) throws IOException
  4. You may now use stdin.readLine(); to read in a String
  5. To compare Strings, use .equals() like so: myStr.equals("a")
• If the user inputs 'a', then print a message that says "USER SELECTED ADD"
• If the user inputs 'p', then print a message that says "USER SELECTED PRINT"
• If the user inputs 'q', then print a message that says "USER SELECTED QUIT"

Agenda:

• Complete AddressBook class lab assignment
• Demo all assignments

Homework:

• Install the Java JDK on your computer (be sure to choose your corresponding operator system)
• Install Eclipse Classic on your computer (be sure to choose your corresponding operator system on the right)
• Test it out, and let Mr. Bui know if you run into problems

Wednesday (9/22/10)

Warmup:
