Question

ou will create a GUI data entry program to be used to enter Customer Information. This program should be based on the requirements and design you created in previous modules.

It will be a GUI, based either on the Java Swing classes or JavaFX. The program will allow for entry of all fields described in your requirements and include appropriate validations for each field. It will be left to you to decide if the validations methods should be part of the entry program or a separate validation class. You should use exception objects to reject invalid data, inform users and allow the program to fail securely. When a complete, correct Customer record has been completed, the user must be able to write the data to an encrypted file.

The requirements:

fields for first and last name, address, date, product, phone, secondary phone, email, complaints, employee name, employee id.

Build this as a project for your application and compress and submit the entire project file. See the Course Documents, Submitting Your Programs for more detail.
