Coding In Java - pls help

1. From main, ask the customer which paint color they wish to purchase and how many full gallons of
paint are needed. Design your program to allow the customer to make additional purchases of either
color of paint.
2. Establish separate methods to deal with each color of paint:
• A method for the color1 paint: determine the cost of the paint based upon $21.95 per gallon.
o Return the total cost of gold paint to main
• A method for the color2 paint: determine the cost of the paint based upon $19.95 per gallon.
o Return the total cost of green paint to main.
3. A separate method to print the store title for billing purposes.
4. A separate method to determine the total bill for a customer. This method will receive the totals
from the two paint methods, will compute the final total cost, and will add Michigan’s sales tax to the
order. Return this final total to main.
5. Establish a separate method to print a thank-you message for “buying at this store”.
6. Print a bill for the customer. The bill is to be developed in the following order:
• the store name
• the total cost of each paint color listed individually
• the calculated sales tax
• the total bill including sales tax
• the thank you message.
7. Be sure that the amounts are printed as money amounts with dollar signs &
rounding where appropriate.
8. Given the number of methods in your program, be sure to include comments before each indicating
what they do, what they get (if anything) and what they return (if anything).
8. To earn 100% on this program you must include some sort of “SPIFF” of your choosing. What is a
“Spiff”? A spiff is to add something that is not included in the program specifications to make it
‘spiffy’. Typically is some additional feature that presents to the user, but it could also be some sort of
code-structure ‘under the hood’ such as code tools/techniques not already encountered in class. Just be
sure that your spiff is not the same as someone else’s spiff! Be sure to include comments in your code
indicating what your spiff is!

Answer 1

The Java program for paint purchases should involve user input, calculation methods for each paint color based on price per gallon, and methods for printing billing details and thank you messages. It should be properly formatted with comments and include a "spiff" for additional functionality or user experience.

Step-by-step explanation:

Writing a Java Program for Paint Purchases

Creating a Java program to handle paint purchases involves several components:

• User input for selecting paint colors and the quantity needed.
• Separate methods for calculating the cost of each color of paint based on the price per gallon.
• A method for printing the store title and a separate method for printing a thank you message.
• A method to compute the total bill, including Michigan's sales tax, and return it to the main.
• Formatting the output to look like a proper bill with monetary amounts.
• Inclusion of a "spiff", an additional feature that enhances the program's functionality or user experience.

It's also important to include comments before each method to describe its purpose, the inputs it receives, and the value it returns. For example:

// Method to calculate the cost of Gold paint
// Receives the number of gallons as an argument
// Returns the total cost of the Gold paint
public static double calculateGoldPaintCost(int gallons) {
return gallons * 21.95;
}

Finally, the bill should be printed in an organized manner, and the final total should include rounding where appropriate to ensure the amounts are presented as money. Your spiff could be a feature like a loyalty discount that applies when a certain quantity is purchased or an aesthetic improvement in the bill presentation.
