Address Book

Wrte a java application to maintain an address book. Each entry in the address book contains a name, address and phone number. The list of entries should be kept in a file on disk. There are two types of entries, a personal entry and a business entry. A bussiness entry contains an additional phone number for daytime calls and a personal contains a birthday in the form of mm/dd/yy. You can keep this date as a string of characters. The application should provide a GUI to: 1. List all the names sorted by last name. 2. List the address and phone number for a selected name. For personal entries display the birthday and for bussiness entres display the daytime phone number. 3. For a selected name you should be able to modify the address and phone number. For a personal entry you should be able to modify the birthday and for bussiness entries you should be able to modify the daytime phone number. A seperate dialog box should be used to allow the user to make the modifications. 4. You should be able to delete a selected name. 5. Add a new name. a seperate dialog box should be used to allow the user to enter a new address book entry. You can use the same dialog box for viewing, modifying and adding an entry. 6. The entries should all be read into memory when the application begins. Entries should be added, modified and deleted in memory. When the application ends, the file of entries should be rewritten. 7. The application should provide for the case of an empty file of entries. This will be the case the first time the application starts and if all names and addresses are deleted. In this case the file exists but has no data. 8. All classes except the one in main should be kept in a package called addrbook. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
