Question

Please write this code in JAVA lang., thank you!

Your spouse's cousin's nephew's dog's trainer's best friend owns a restaurant. That person is very bad at math and recently discovered that most customers have been significantly undercharged for meals.

You have been approached to create a computer program that will accurately calculate bills for each customer.

Kids, under 5, eat free.
Teens and seniors get a 25% discount.
Also,

Food and beverage is taxed at 5%.
No tax for anything a senior or teen orders and eats.
Every person who eats at this restaurant orders exactly three items. Never greater, never fewer.

The menu is limited:

Menu Item

Price

Soup

2.50

Wings

.15 each

Burger

4.95

Chicken sandwich

5.95

Fries

1.99

Pie

2.95

Ice cream

2.99

Soft drink

1.50

Coffee

1.00

Write a program that will accurately determine a bill.

Programs must be tested. In order to test this program, use the following scenario.

A family stops at the restaurant for lunch. The family is composed of a middle aged mother and father named Bill and Nancy. They have a 2-year old child named Jesse. They are traveling with Nancy's elderly grandmother, Sarah.

Everybody decided to order a burger. Nancy and Jesse order a soft drink. Nancy and Sarah order soup. Bill orders 5 wings. Bill and Sarah order coffee. Jesse orders ice cream.

Run your program one time for each person and determine the grand total this family would owe on their bill.
