Question

Java Programing

Display any welcome message at the top of the output screen

Create following variables:

Price for a cup of coffee (make it adjustable within the program)

Number of cups (response from User)

Tax Rate in San Diego is 8%. Define 8% as a CONSTANT variable that never changes

Payment Method (Cash, Credit Card, Store Credit, Gold)

Ask the customer for their first name, and store it as a String object.

Ask the customer (by name) how many cups of coffee they would like to order and save that value.

Calculate the Total (# of cups * Price per Cup) * Sales tax

Using the printf, make all currency data printed to the screen display 2 decimal places, and also a '$" sign.

Also use at least one Decimal Format print method .

Using a switch statement on the payment type

If the user entered 'm' or 'M', display "You are paying using money" to the screen.

If the user entered 'c' or 'C', display "You are paying by Credit Card" to the screen .

If the user entered 's' or 'S;, dispay "You are paying with Store Credit" to the screen.

If the user entered 'g' or 'G', display "You are paying with Gold" to the screen.

If the user entered anything else, display "Invalid payment type, no lemonade for you!", and end the program

Using an if statement, If the quantity is less than 1, then display "Get out of my store, you bum!" and exit the program

Using a single if-else-if statement (also called a multi-branch if-else statement)

If the total is less than $10 and the user is paying by credit card, display "Sorry, there is a $10 minimum purchase for credit card"

If the total is between $10 and $100 (including $10 and $100), and display "Thank you, you earned a free glass of Lemonade!"

If the quantity is greater than 50 or the total is greater than $100, display "I'm going to Disneyland!"
