Description

OVERALL INFORMATION – CONTACT NAMES AND PHONE NUMBERS

A Data Structures Information System needs to be written in order to review Collections as found in the Java Collections Framework.

CONTACT NAMES CLASS FILE

The information system needs to hold a collection of contact names and their corresponding numerical phone number.  For example, a contact name such as Mawson, Judith has a phone number of 412-555-1212 (all for illustration only).  Make up at least five for this system.

GRAPHICAL USER INTERFACE PROGRAM

Create GUI programming techniques via a separate .java class file.  You can design more than one GUI .java file but only one is required to interface with the contact names class.

You are NOT allowed to use an interface in an IDE (Interactive Development Environment) that generates the Java code automatically. 

In terms of the GUI (Graphical User Interface), you can use the JOptionPane and/or the Scanner Classes or you can create more advanced GUI’s (using either Swing or JavaFx).

Keep in mind that the GUI class must be a separate .java class file from the contact names class .java file.

The main menu should consist of the following:

Sets

            Create and work with a Set (no Duplicates)

            Create and work with a Set (HashSet)

Lists

            Create and work with an ArrayList

            Create and work with a LinkedList

Stacks

            Create and work with a Stack

Queue

            Create and work with a Queue

Exit

Once the user makes a choice as to which data structure to create, the user should be prompted to enter the data (contact name and their corresponding cell phone number) into the data structure. 

Additionally, the user should be allowed to perform at least four of the following operations on the collection:  (choose the ones you want to incorporate into your program via the predefined methods) add a contact name and its corresponding cell phone number,  delete a contact name and its corresponding cell phone number, search for a specific contact name, and, if it is found, it should then display its corresponding cell phone  number, copy the data structure and then display both collections, sort the collection by contact name, count the number of entries (contacts) in the collection, output the collection in reverse order, or any other operations you want to include.

For each operation, your program should allow the user to display the collection before and after.
