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. Submit assignment per the APA template that will be provided, to include cover page, description of code, flowchart or pseudocode, code with header data, and finally a screen shot of your code executing on your computer.  Please submit your assignment as YourLastNameWk3.doc and YourLastNameWk3.java.  Ensure that your code executes prior to submittal.
