This is a two-part assignment.
Part 1
Design, implement, test, and debug a program with a JFrame that allows the user to enter a

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.
