Question

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.

Which part of this is giving you trouble?

Answer 2

The public static I need to know how to write it

Answer 3

You mean the required parts of Java code?

```
public class ClassName
{
public static void main (String[] args)
