Question

Write an AddressBook class to search the address or the phone of your present friends and to also add new friends to your address book. Then write a Friend class. To do this, you can extend a Person class, which contains only the names of a person. Then you can extend the Person class to a Friend class to hold the additional data fields for the address and phone numbers. It would be also be best to create an Address class and then add an Address object data field to the Friend class.
The application should start by reading an input file ( 4 or 5 lines of data regarding friends is enough). Each line in the input file should have data about the full name of a friend, his/her full address and his/her phone numbers.
Once you read a complete record/line from an input file, create a Friend object for that record. Then use an ArrayList to create a list of Friend objects
Once you finish reading all the records from the input file, display all the Friend objects using the collection object.
Once you read all the input, display the GUI to the user and allow him/her to view, add or to search the list. The buttons in the GUI should allow the user to perform such actions. That is, when pressed:
