Concept explainers
In the following field declaration from the TicketMachine class
private int price;
does it matter which order the three words appear in? Edit the TicketMachine class to try different orderings. After each change, close the editor. Does the appearance of the class diagram after each change give you a clue as to whether or not other orderings are possible? Check by pressing the Compile button to see if there is an error message.
Make sure that you reinstate the original version after your experiments!

- Add additional functionalites to this code. For one room add this riddle, "The shorter I am, the bigger I am. What am I?" And the only way to continue to the next room is to type, "A temper," or "temper." And for another room, a help command. For example, the user will type, "help," and they will be told where to go next so they can each the winning room.arrow_forwardPLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS. PLEASE EDIT BOTH THE TEST CLASS, DO NOT EDIT THE MAIN METHOD. Write a BankAccountTester class whose main method constructs a bank account, deposits $1,000, withdraws $500, withdraws another $400, and then prints the remaining balance. Also print the expected result.arrow_forwardThis is a new homework assignment. Fill in the blanks.arrow_forward
- THIS DOESNT WORK WITH THE TEST CLASS PROVIDED, PLEASE ENSURE THAT IT DOES!arrow_forwardIn this assignment, you will need to add a new method to the Date class, which you can find on D2L in the "Sample Code" section. The new method should make a Date object's day, month, and year value change to the next day. In other words, add one day to the object's current date. Do not use any part of the built-in DateTime class, but you may want to use the DaysInMonth() method from the Date class. Examples: • If the Date object stores the date 12/31/2021, then after calling your method it should store the date 1/1/2022 • If the Date object stores the date 2/28/2022, then after calling your method it should store the date 3/1/2022 As noted in the common instructions, you only need to turn in your new method, not the entire Date class.arrow_forwardCan you draw a class diagram on the text with the appropriate classes, attributes, methods, and relationships. (Please use the draw.io web site for drawing.) Here are the main classes and their relationships: HoneynetCentralServer Attributes: cronjobInterval Relationships: has many Honeypots has a LogProcessor Honeypot Attributes: ipAddress, sshCredentials Relationships: has many LogEntries LogEntry Attributes: timestamp, message, actionType (e.g., delete, create in FTP), attackLevel (low, medium, or high) Relationships: belongs to a Honeypot LogProcessor (Nodejs tool) Attributes: ruleFilters Methods: processLogEntries(logEntries) Relationships: processes LogEntries MongoDBAtlasDatabase Attributes: connectionString Methods: storeLogEntries(logEntries) Relationships: stores LogEntries ManagementTool (ElectronJS) Attributes: graphicalLibraries, visualLibraries Methods: displayData(data) Relationships: displays data from MongoDBAtlasDatabase ExternalAPI Attributes: apiUrl,…arrow_forward
- SELECT ALL the members of the class that are accessible by classes in the same package as Bicycle. Take note: In your response, leave off the constructor(s).arrow_forwardThe code given below represents a saveTransaction() method which is used to save data to a database from the Java program. Given the classes in the image as well as an image of the screen which will call the function, modify the given code so that it loops through the items again, this time as it loops through you are to insert the data into the salesdetails table, note that the SalesNumber from the AUTO-INCREMENT field from above is to be inserted here with each record being placed into the salesdetails table. Finally, as you loop through the items the product table must be update because as products are sold the onhand field in the products table must be updated. When multiple tables are to be updated with related data, you should wrap it into a DMBS transaction. The schema for the database is also depicted. public class PosDAO { private Connection connection; public PosDAO(Connection connection) { this.connection = connection; } public void…arrow_forwardYou are to implement removeHead, and removeTail and you also have to create the following functions (for visual purposes of the detail explanation, header and trailer sentinels are described as h and t respectively): IMPORTANT NOTE: For all the methods that has the pos parameter i.e. addAt, removeAt, move, make sure to access that specified position from whichever is nearer - the head or the tail - similar to what we have done in the get method. Example DoublyLinkedList: h <-> 10 <-> 30 <-> 40 <-> 50 <-> t int add(int num) This will add the element num into the last element of the linked list and return the position of the newly-added element. In the above example, having add(60) will return 5 as it is the fifth position in the list. int remove(int num) This will remove the first instance of the element and return the position of the removed element. In the above example, having remove(40) will return 3 as 40 was the third element in the linked list…arrow_forward
- Write out what you think the outer wrappers of the Student and LabClass classes might look like; do not worry about the inner part.arrow_forwardAdd additional information to the student class below such as name, address, major, and contact information along with all the getters and setters (methods) needed to access all data. Submit your code along with a sample run of your program. Comment all your code. Cite any sources of information you use. Write a note on the process of completing the assignment in a Microsoft Word document. // ShowStudent.java // client to test the Student class class ShowStudent { public static void main (String args[]) { Student pupil = new Student(); // We need a new student named pupil pupil.setIDnumber(234); // We are setting pupil's ID number to 234 pupil.setPoints(47); // We are setting pupil's points to 47 pupil.setHours(15); // We are setting pupil's hours to 15 pupil.showIDnumber(); // We are showing pupil's ID number pupil.showPoints(); // We are showing pupil's points pupil.showHours(); // We are showing pupil's hourse System.out.println("The grade point average is " +…arrow_forwardThis is the question I am stuck on - A. Create a CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Create a Student class containing an ID number and an array of five CollegeCourse objects. Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4). Next, create a set method that sets the value of one of the Student’s CollegeCourse objects; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4). B. Write an application that prompts a professor to enter grades for five different courses each for 10 students. Prompt the professor to enter data for one student at a time, including student ID and course data for…arrow_forward
