Question

Write a program for XXX Phones, a provider of cellular phone service. Prompt a user for maximum monthly values for talk minutes used, text messages sent, and gigabytes of data used, and then recommend the best plan for the customer’s needs. A customer who needs fewer than 400 minutes of talk and no text or data should accept Plan A at $29 per month. A customer who needs fewer than 400 minutes of talk and any text messages should accept Plan B at $35 per month. A customer who needs 400 or more minutes of talk and no data should accept either Plan C for up to 100 text messages at $45 per month or Plan D for 100 text messages or more at $50 per month. A customer who needs any data should accept Plan E for up to 2 gigabytes at $59 or Plan F for 2 gigabytes or more at $65. Save the file as CellPhoneService.java

Again, Don’t forget to create the application/project CellPhoneServiceTest.java Class that has the main method and an object to use the CellPhoneService class.
