C omplete Java program with the following specifications: Display a welcoming message such as: quot;Welcome to Calculator Program!

Complete Java program with the following specifications:

Display a welcoming message such as: "Welcome to Calculator Program!"

Prompt the user twice to enter two positive whole numbers, indicating first and second

values, first value being smaller than the second one

Calculate the square and cube of each number from first value to second value inclusive and

then display an appropriately headered three column table with each row containing the

number, its square and its cube respectively

Display a farewell message such as: "Goodbye, thank you for using our program!"

As an example, if the starting and finishing values were 2 and 4 respectively, the table in the output

would look something like the following:

Number Square Cube

2 4 8

3 9 27

4 16 64

Ensure that the program is appropriately documented throughout and thoroughly tested to demonstrate

its correct operation.

You may assume that the user of the program enters the inputs as required so that no input validation

or error checking is necessary.

You need to submit java and class files, a short discussion to explain the logic on how the problem has

been solved, and sample output (for detail please see marking guide and presentation below).

Task 5:

Problem Description:

Complete Java program to calculate the total charge corresponding to purchase of books at a

fictional annual book festival. The price of each book is based on its category as described below:

Large print hardback books $10 each or three for $20

Small print hardback books $7 each or two for $10

All softcover books $5 each or five for $15

An example run of the program might look like the following (user input is shown in bold):

Welcome to the annual book festival!

Enter the number of large print hardback books purchased: 4

Enter the number of small print hardback books purchased: 6

Enter the number of softcover books purchased: 7

Your total bill is: $85

Would you like to calculate another bill (y/n)? y

Enter the number of large print hardback books purchased: 6

Enter the number of small print hardback books purchased: 0

Enter the number of softcover books purchased: 10

Your total bill is: $70

Would you like to calculate another bill (y/n)? n

Total sales in this session: $155

Goodbye!

Note that the program will continue calculating bills until the user enters n in response to the last

prompt asking if another calculation is required.
