Week 3 Individual Assignment

 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.
