Analysis: Q1: There are common attributes and methods between passengers and drivers. What is the best choice for designing and writing the codes of these two classes? Explain your answer. Q2: Draw a simple class diagram showing only relationships between the classes. Implementation: After analysing the given requirements, implement the required application: with Object Oriented Programming style following the rules of good programming style (e.g. adding comments, etc.) • using only the material covered in M251 (and its prerequisites) Java language*

There are common attributes and methods between kids and trainers. What is the best choice for designing and writing the codes of these two classes? Explain your answer. þraw a simple class diagram showing only relationships between the classes. Implementation: After analysing the given requirements, implement the required application: • with Object Oriented Programming style tellowing the rules of good programming style (e.g. adding comments, etc.) using only the material covered in M251 (and its prerequisites) Hints: For each class, it is required to implement constructors, setters, getters, tostring() method, and any other necessary method If the user tries to do an operation that could violate the state of objects, the operation should bejenered and the application should display an error message (e.g. adding a kid to the same group twice, etc.) Checking equality of any 2 objects should be done via the equals() method There is a class that will do the main job of keep tracking of…
This is the question: 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 Figure 5.5 on page 180 of the textbook. 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 theleft. 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…
Please give the class diagram of the system and see if there is any problem in the operation of the classes
UML diagram analysis: refer to the following UML diagram of the Loan Class. a) How many instance variables does the TV class have? b) How many methods that return a value does the TV class have? c) How many static methods does the TV class have? d) How many constructors does the TV class have? e) How many defaults data fields does the TV class have?

Answer the following questions based on knowledge of inner class: Please answer according to question please please.
Using UML class diagrams, create a design for the following (you can defer declaring the types for any instance variables and instance methods as long as you represent the concepts appropriately). NB: You may hand-draw your diagram or use a drawing program (your choice). Upload your finished answer for (a) and (b) as one file. (a) An Employer has one or more Employees. An Employee has exactly one Employer. Employees have attributes for their name, salary and job title (b) We are producing a vehicle registration system for the local DMV/RMV. Model the following using a UML class diagram. Read the entire specification before proceeding (this is ONE question, broken into 4 segments for readability): (i) Our interface (protocol/contract) IVehicle states that all vehicles can register() and calculateExciseTax(). These operations are public and the Vehicle contract is stable – it will not change. (ii) We think we’ll be able to take advantage of code-reuse, so your team must introduce an…
For this problem you are to join the following classes into a hierarchy (use the UML diagrams from Module 2 to get started): Player - Super Class Archer - Subclass Barbarian - Subclass Cleric - Subclass Rogue - Subclass Warlock - Subclass If the parent class has the same attributes as the sub class then you can remove those attributes from the subclass. If the class is new for this module, please come up with 2 unique attributes of your choice, and 1 piece of functionality. If the sub classes are shown on the same level, then they share a parent class.
ABC Blood bank wanted to fix the cost for all types of Blood group according to the availability of them. They planned to fix the cost in such a way that the rarely available Bloodgroups are charged high compared to the others. Write a program to get the Blood group and the cost for all blood groups, help them to display the blood group with the lowest cost using a parameterized constructor. Strictly adhere to the Object-Oriented specifications given in the problem statement. All class names, member variable names, and function names should be the same as specified in the problem statement. The class Blood has the following private data members. Data Type Variable Name string blood_group int cost Include appropriate default and parameterized constructors for the above class.Include the following method in the Blood class Method Member Functions void display(Blood obj[], int n) This method is used to display the details of the blood group with the lowest cost.Display…
Hi, this is a java programming question with direction of what to do. I'm just gonna attach the question sheet. Implement the following class diagram (diagram in attached photo)setFirstName() method should set the firstName attribute of the class.setLastName() method should set the lastName attribute of the class.setSpecialization() method should set the specialization attribute of the Doctor class.setHealthnumber() method should set the healthNumber attribute of the Patient class.setIllness() method should set the illness attribute of the Patient class.If you are not comfortable with set methods, you are free to create your own constructors to set the attribute values.Create a HospitalApplication class which contains the main method. Inside the main method the following should be done in the order mentioned. (Any other ordering would not guarantee full marks).Prompt for the following inputs for 5 Doctors. (Use for loops)• First name• Last name• SpecializationValid specializations…
I'm curious to know what "association class" means.
List all of the main stages that were taken in the process of finding classes in the class-based approach. The response is satisfactory. solely in the form of bullets Don't go into great detail about each step.
