Assignment 8.3: Phone Chatbot (10 pts)

• For this programming assignment, we write a basic chatbot program.
• For fun, try having a conversation with an online chatbot here or here.
• Some sources estimate that 25% of customer services will be handled by Chatbots in 2020, vs. 2% in 2017 (1).
• The chatbot we are designing must ask you the following questions:

1. What is your name?
2. What is your phone number?
3. What is your phone plan?
4. How many GB of data this month?

• Just don't give the chatbot your credit card number!

Project Specifications

• Write a chatbot program that interacts with the user as described in the Interaction section below to calculate a phone bill.
• Name the source code file Phonebot.java and include all your code in this single file.
• Be careful of the spelling, including capitalization, as you will lose points for a misspelled name. Naming is important in programming.
• Interaction: Interact with the user with the following inputs in the order given (and no other input) as follows:
• Name: open the conversation with a welcome and find out the user's name (String).
  • Reply with a greeting that displays the user's name, like "Thanks for calling RobuCast !".
• Phone: find out the user's phone number (String).
  • Reply with a statement like "Looking up phone number ...".
• Plan: ask the user for their plan type entered as a basic, gold or unlimited
  • Reply by spelling out the full plan name, (basic package, gold members, unlimited plan)
• Data: request user's data usage in Gigabytes (double).
  • Reply with a comment that restates the amount of data, such as "Wow, is a lot of data! You should upgrade."
• Total: display the total bill and say goodbye to .
• The parenthesis show the required data types for the input. Make sure to restate the input where indicated by the word "reply" or angle brackets.
• Assume the user enters only valid data.
• The phone bill is based on the phone plan and the number of Gigabytes (GB) of data used per month. Here are the different plans:
  • Basic package: the $24.95 per month plan provides 2 GB of data. Additional data are $7.00 per Gigabyte.
  • Gold member plan: the $39.95 per month plan provides 5 GB of data. Additional data are $5.00 per Gigabyte.
  • Unlimited plan: the $59.95 per month plan provides unlimited data.
• Hint: Assume that the user input will be one word responses at most. Use only input.next() statements in this program (no input.nextLine() statements).
• Example Output: The following shows example outputs. Your program prompts and output does not have to exactly match mine.
• Your program does need to reply to all input as stated in Interactions above, but you are free to give your chatbot a personality.
• Make sure the inputs are in the correct order and that you restate the data entered by the user.
• Otherwise, have fun with it!
• When you are finished, upload your PhoneBot.java file to Canvas
