Question

How much more time is needed for the answer?

write pseudocode to design a phone contact list program. Your program includes a Graphical User Interface that allows user to add new contacts, update existing contacts, search specific contact from the contact list, sort the csntact list in ascending or descending order, delete an old contact. Your program should also provide help screen, an exit button to close the program and displays error messages for any exceptions.

Input:

-Write a data text file with a list of phone number (10 digits with dashes, 555-555-5555)

-Read text file to retrieve contact info (phone number, first name, last name)

* Read the file into memory (hint: parallel arrays)

-Individual contact info can also be entered from the keypad

Process: (open/read the file, display the menu, close file)

-Maintain the phone list by ADD, UPDATE, DELETE, INQUIRE/SEARCH, SORTING

*When each item on the menu is done, redisplay the menu

Output: (per each navigation menu item)

-Design a GUI screen that include

*Keypad with numbers

*Navigation menu

*Add New Contact ( textbox for first name, last name, textbox for phone number)

*Update Contact (search by phone number to display name and phone OR search by name to display name and phone number)

*Delete Contact from List (change name to blank)

*Inquire: enter phone name or name

*List: Sort list either ascending or descending order by first name or last name

*Help

*Save phone list

*Exit

-Define a CONTACT class

*Fields (phone number, first name, last name)

*Set & get method

*Constructor

*Methods (add, update, delete, save, sort, display the list etc. )

-Object: personal contact list Or company phone directory (inheritance)

*Public class PersonalContact extends Contact { }

Add:

Enter phone number (phone number: range 1-999)

If not found – display message

If name is blank, enter name (first and last)

If name NOT blank, save contact info, display confirm message

Change:

Enter phone number

If not found – display message

IF found – display name and ask for new name

If name is blank, ask for new name

Delete:

Enter phone number

If not found – display message

If found – display name and confirm delete

If confirm is yes – blank out name

If confirm is no – return to menu

If name is blank, display message

Inquire:

Enter phone number

If found – display name

If not found – display message

If found and name is blank – display message

Sort:

Question: sort ascending, descending or return to menu

If return to menu, then return to menu

If ascending- sort phone number ascending

If descending - sort phone number in descending order

After sort, display phone list

Help:

Display menu option and a one description of the function

Save:

Write phone list back to file

Exit:

If file is open, save phone list, close file

Terminate program

Error:

If a menu selection is made that is not displayed (1-9)

Issue message and display the help screen

Can the answer be written in a genral form so that each statement in the pseudocode represents an operation that can be performed in any high-level language please?

Like this forexample:

Module main( )

// Display the starting message....etc.

Call startingMessage( )

Display "Press a key...etc.

Input

// Display Step 1.

Call step1( )

Display "Press key...etc.

Input

End Module
