Question

create a java code with scanner and formatt

Write a generic program to find the total cost of the business trip by creating a class file called lastname_trip_cost.java. Add three instance variables for the type of airline ticket, the type of hotel and the total number of nights staying at the hotel. Add methods to return values for

* the cost of airline ticket

* total number of days less than complete weeks

* total number of whole weeks

* cost of hotel

Create a file called lastname_trip_cost_demo.java. In this file add an object to pass the three values to the class. Add statements to print the values shown in the output.

Round trip airfare rates from New York to Orlando   
Economy class $300.00   
Business class $800.00   
First class $1,000.00   

Hotel Rates Daily Rate Weekly
3 Star Hotel $120.00 $750.00
4 Star Hotel $160.00 $1,000.00
5 Star Hotel $200.00 $1,250.00

User Input:   
Enter the type of airline ticket - 1 for Economy, 2 for business and 3 for First class = 2
Enter the type of hotel - 1 for 3 star, 2 for 4 star and 3 for 5 star = 1
Enter the total number of nights staying at the hotel = 15

Expected Output:   
Cost of airline ticket = $800.00
Total number of days less than complete weeks = 15 - 7(2) = 1
Total number of whole weeks = 2
Cost of hotel = 750(2) + 120(1) = $1620
Total cost = 800 + 1620 = $2420
