create a customer management application in java swing that uses a binary file I/O for storing customer information? The application should include data validation and exception handling. With this management application, a user should be able to perform the following operations: 

• Add new customer, only if all the valid information is provided
• Find and modify existing customer using customer id
• Display list of all customers

And for each customer following information is kept:

• Customer id (integer and unique)
• Name, Phone, Email, and Postal Code

Thank you
