Task #2 Write Java program, with at least two modules or functions, that will modify the above program so it also calculates and displays the amount of money Package A customers would save if they purchased Packages B or C, and the amount of money Package B customers would save if they purchased Package C. If there would be no savings, no message should be printed. This time the program should (1) use constants to represent the base rates and base hours, and (2) use DecimalFormat class to define format pattern and print total charges and total savings with $ in the front and two digits after decimal point with trailing zeros displayed.
The following are sample interactions that occur when running the program:
$ java InternetServiceProviderPart2
Enter the customer's package (A, B, or C): A
Enter the number of hours used: 10
The charges are $9.95
$ java InternetServiceProviderPart2
Enter the customer's package (A, B, or C): A
Enter the number of hours used: 20
The charges are $29.95
With package B you would have saved $16.00
With package C you would have saved $10.00
$ java InternetServiceProviderPart2
Enter the customer's package (A, B, or C): A
Enter the number of hours used: 30
The charges are $49.95
With package B you would have saved $26.00
With package C you would have saved $30.00
$ java InternetServiceProviderPart2
Enter the customer's package (A, B, or C): B
Enter the number of hours used: 777
Invalid input, please enter number of hours between 0 & 720.
Let's try again.
Enter the customer's package (A, B, or C): B
Enter the number of hours used: 40
The charges are $33.95
With package C you would have saved $14.00
$ java InternetServiceProviderPart2
Enter the customer's package (A, B, or C): C
Enter the number of hours used: 100
The charges are $19.95
