Hello guys!
Assignment!
C.
Exercise
An Internet Service provider has three different subscription packages for its customers:
Package A: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour.
Package B: For $13.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour.
Package C: For $19.95 per unlimited access is provided.
Write a program that calculates a customer’s monthly bill. It should ask the user to enter the letter of the package the customer has purchases (A, B, C) and the number of hours that were used. It should then display the total charge. The program will also calculates and displays the amount of money Package A customers would save if they purchased Package B or C, and the amount of money
Package B customers would save if they purchases Package C. If there would be no savings, no message should be printed.
This assignment will require using a switch statement to check the different package type (A, B, or C). It requires to use System.out.printf( ) method to output the messages instead of System.out.println( ) or Systemout.print( ) or a dialog box. It requires formatting the input and output the same style as shown below in the sample runs.
What I have gotten so far. I just don't know how to use a if/else statement in a switch statement.
