Contact Data

Week 3 Individual Assignment

Part 1

Design, implement, test, and debug a program with a JFrame that
allows the user to enter a series of contacts’ names, ages, e-mail
addresses, and cell phone numbers, and creates a file from the
entered data.

Validate the age entry to ensure that it is numeric and
between 0 and 120. Include information for three to five contacts.
* Part 2

Design, implement, test, and debug a program that reads the file you
created by the list in Part 1 and displays the records in a JFrame.

You may either display all entries in the list at once or display them
one at a time; the user interface is up to you.

Protect against not being able to open the file.
