Draw the UML diagram for the class and then implement the class. For more details about UML diagrams see the “UMLNotation.pdf” by Y. Daniel Liang, located in LabFiles folder. Discuss: Should the class Square have a main method? Use lab_02 as the name of this Java Application project.
In this activity, we are going to plan out and write a class definition that stores information for a book. Let's say we want to store the following information about this book: The book's name The book's author(s) (a book can have more than one author) The book's publisher The book's ISBN number The book's price The book's year of publication First, answer the following questions before the design: 1. What is a suitable name for this class? (Pick a name that best describes it).

please I want a class diagram for university student club application. The application has the university clubs the user can search for any club they want to know about also the user can registor in the clubs through the application and of the user have any questions they can ask through the application. also there will be an inclination test the user can take to see which club is sutiable for them. Make sure that the class diagram is has all the components in the use case for our system. please I want the class diagram to be correct This is the use case diagram for our application please I want a class diagram for the application, and please I want the class diagram to draw it using an application not by hand please
Create a UML diagram to document the Cuboid class. You can model this class after the Rectangle class we covered in this chapter. It should have 3 data fields: width, length, height. It should have 3 accessors and 3 mutators. It should have a method that calculates the volume of the cuboid. Save your file in MS Word or PDF format. Hint: In MS Word, you can create a table of 1 column and 3 rows. What is a cuboid? You can consider a cuboid as a cube whose length, width, and height may not be equal to each other.
Design and implement a class called Bug, which represents a bug moving along a horizontal wire. The bug can only move for one unit of distance at a time, in the direction it is facing. The bug can also turn to reverse direction. For your design, create a UML Class diagram similar to that on the attachment. Note that you need to include the constructor in the methods section if you code a constructor. Bug will require a toString method to return the current position and which direction the bug is facing to the driver so it can be output. Hint: Remember that a horizontal line has a zero position in the middle with positive to the right and negative to the left. Consider that a bug will land on the wire at some point before starting along the wire. Write an interactive test driver that instantiates a Bug, then allows the user to manipulate it with simple commands like Output (to see the position and direction), Move, Turn, Exit ... single letters work just fine. All output…
Help, I am making a elevator simulation using polymorphism. I am not sure to do now. Any help would be appreciated. My code is at the bottom, that's all I could think off. There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators. public abstract class Passenger { public static int passangerCounter = 0; private String passengerID; protected…

Create a TestCard project with a TestCard class and a Card class. Data members for the Card class should be two numeric values representing the suit of the Card and the card's number. The Card class also has a constructor and methods for setting and getting the card information. See UML model. In the TestCard class within main(), deal two cards at a time by constructing two card objects. One card is the user's. The other is the computer's. Show both cards. Add a point to whoever had the higher card. Show who won the trick and the score. Scores don't change if a tie. Keep dealing until user wants to quit or 26 pairs have been dealt. UML for Card class -suit: int the number that corresponds to the suit of the card. 0 Hearts, 1 Diamonds, 2 Clubs, 3 Spades -value: int the value of the card. Ace is 1, 2 is 2, ..., Jack is 11, Queen 12, King 13. +Card() Default constructor. Sets the suit and number to random values +getValue(): int Returns the value of the…

Draw a UML usecase diagram of the Habit tracker. A habit tracker is designed for ease of users to track daily behaviors. The application allows the user to add a habit. Each time the user adds any habit, the habit history is updated. When the user perform his habit, he mark the habit as done today and can also add a comment only if he wants. And the same is updated the habit history. A user is also allowed to delete a habit. Each time a habit is deleted the habit history is Updated. Both the user and a coach is allowed to list habits and view the habit history. In habit history view, single habit check-in can also be viewed. However, the coach is also allowed to list all the users and can view one user’s habit separately if he wants
