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.

Implement all the classes using Java programming language from the given UML Class diagram. Note: This problem requires you to submit just two classes: Customer.java, Invoice.java. Do NOT include "public static void main()" method inside all of these classes. Graders will be testing your classes, using the unit-testing framework JUnit 4. Customer - ID:int -name:String -discount:int Discount rate in percent +Customer(ID:int,name:String, discount:int) +getID():int +getName ():String +getDiscount():int +setDiscount(discount:int):void +toString():String "name (ID)" The Customer class models, a customer design as shown in the class diagram. Write the codes for the Customer class and a test driver to test all the public methods. Invoice - ID:int

A mountain climbing club maintains a record of the climbs that its members have made. Information about a climb includes the name of the mountain peak and the amount of time it took to reach the top. The information is contained in the ClimbInfo class as declared below. The ClimbingClub class maintains a list of the climbs made by members of the club. The declaration of the ClimbingClub class is shown below. You will write implementations of the addClimb method. import java.util.List; import java.util.ArrayList; class ClimbInfo { private String name; private int time; /** Creates a ClimbInfo object with name peakName and time climbTime. * * @param peakName the name of the mountain peak * @param climbTime the number of minutes taken to complete the climb */ public ClimbInfo(String peakName, int climbTime) { name = peakName; time = climbTime; } /** @return the name of the mountain peak */ public String getName() { return name; } /** @return the number of minutes…
