Week 6 - Practice Programming -- For Netbeans// Java
Question: Make an address book application that stores your contacts in a database. First, set up a database with at least one table for the contacts. The fields should include the contact's name, phone number, and email address.
Then create a JTabbedPane GUI with two tabs: an Add tab that lets the user enter the information for a contact and add it to the database, and a Display tab that shows all of the contacts in the database.

Business Contact Subclass:

Personal Contact Subclass:
package contactlist;
