Travel Tickets Company sells tickets for airlines, tours, and other travel-related services. Because ticket agents frequently mistype long ticket numbers, Travel Tickets has asked you to write an application that indicates invalid ticket number entries. The class prompts a ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you drop the last digit of the number, then divide the number by 7, the remainder of the division will be identical to the last dropped digit. Accept the ticket number from the agent and verify whether it is a valid number. Test the application with the following ticket numbers: . 123454; the comparison should evaluate to true . 147103; the comparison should evaluate to true . 154123; the comparison should evaluate to false Save the program as TicketNumber.java.

Microsoft Visual C# 7th edition : Create an application named CarDemo that declares at least two Car objects and demonstrates how they can be incremented using an overloaded ++ operator. Create a Car class that contains the following properties: Model - The car model (as a string) Mpg The car's miles per gallon (as a double) Include two overloaded constructors. One accepts parameters for the model and miles per gallon; the other accepts a model and sets the miles per gallon to 20. Overload the ++ operator that increases the miles per gallon value by 1. The CarDemo application creates at least one Car using each constructor and displays the Car values both before and after incrementation. here is my code. Thanks for helping me. using static System.Console; class CarDemo { static void Main() { Car red = new Car("Civic", 38.50); Car blue = new Car("Corolla"); WriteLine("{0} {1}", red.Model, red.Mpg); WriteLine("{0}", blue.Model); // Write your main here. }…
Create an application named SalesTransactiobDemo that declares several SalesTransaction objects and displays their values and their sum. Name - The salesperson name (as a string) sales Amount- The sales amount (as a double) commission- The commission (as a double) RATE- A readonly field that stores the commission rate (as a double). Define a getRate() avcessor method that returns the RATE Include 3 constructors for the class. One constructor accepts values for the name, sales amount, and rate, and when the sales value is set, the constructor computes the commission as sales value times commission rate. The second constructor accepts a name and sales amount, but sets the commission rate to 0 The third constructor accepts a name and sets all the other fields to 0

in C#, Visual Basic Create a Car class that has at least the following properties:• Year• Make• Price• Passengers-holds the number of seat belts available in the car (presumably how many passengers the car can hold). This field must be private since users presumably can’t change this value. Have two constructors: one that initializes everything to some default value for the base price of a car and one that also accepts values for luxury upgrades of: heated seats, sun-roof, and satellite radio. The class has two methods: 1) Get Paint Color() which accepts a standard base color option but allows the user to purchase a pricier customized color 2) Upgrade Costs() which computes the cost of user-selected luxury items and adds it to the price. Create three car objects: Ford (make Explorer), Lexus (make ES) and a Clown Car which overrides the passenger value to allow 20 clowns in the car. The Get Paint Color() and Upgrade Costs() functions needs to be called for each object and data for all…
