A. Declaring and defining the class: The class must consist of the following members: • Attributes • Constructors (at least two) and destructor Accessors and mutators (for all the attributes, and you may add more) Display-related methods. Methods regarding showing or displaying the objects onto the screen. (for example, the mehods draw (), undraw (), etc) Action-related methods. Methods that perform the key actions of the objects (for example, for the Pac-man, the mehod could be run () , eatenByGhost (), catchGhost (), hitWall(), etc). B. Separations of class declarations and definitions as well as the application program into different files. C. Creating object(s) and letting the object(s) to perform their actions. for example, . some examples scenario for the pac-man class • a pac-man (or pacmans) run(s) from one side to the other side of the ... screen the pac-mans might be colliding one to another and when this happens, they will die or might be bouncing back) • the pac-mans change their direction of movement when the user/player presses arrow keys

Define a new "Exam" class that manages the exam name (string) and its score (integer). For example, an exam can have - "Midterm Exam", 100 - "Final Exam", 50 The class must not provide the default constructor. It must require the exam name and score in order to initialize the Exam object. The class must provide only the following methods (no more and no less): - isPerfect method that returns true if the score is exactly 100 and false otherwise. - isPassing method that returns true if the score is equal or greater than 70 and false otherwise. - toString method must return all the exam information including the result of the exam as a string in the following format: EXAM(<name>) SCORE(<score>) RESULT(Pass/Fail) such asEXAM(Midterm Exam) SCORE(100) RESULT(Pass) EXAM(Final Exam) SCORE(50) RESULT(Fail) "Pass" means the score is greater or equal 70. "Fail" is whenever the score is below 70. - isGreater method that compares with another Exam object and return true if the score…
Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…
Design and implement a class called Car that contains instance data that represents the company, price, model, and year of the car. Define the Car constructor to initialize these values. Include getter and setter methods for all instance data, and a toString method that returns a one-line description of the car. Create a driver class called CarTest, whose main method instantiates array of Car objects and write the following methods: 1) Method “printInfo” that receives an array of cars and returns all information about all cars. 2) A Method called getTopByCompany that receives an array of Cars and then returns an array of cars containing the cars that have the highest price compared with cars from the same company.
Add comments as appropriate. Be sure that your program output is neatly presented to the user. Add documentation comments to your functions. You are going to change the class you created in Program7 so that it has a constructor and some properties. In your GeoPoint class make the following changes (note your variable, parameter and method names may be different. Adjust as needed.): Add a constructor __init__(self, lat=0, lon=0,description = ‘TBD’) that will initialize the class variables __lat ,__lon and the __description. Notice that the constructor will also default lat and lon to zero and description to ‘TBD’ if they are not provided. Change the SetPoint method so that instead of individual coordinates SetPoint(self, lat, lon) it takes a single sequence. Add a property: Point = property(GetPoint,SetPoint). Make sure GetPoint and SetPoint are the names you used for the get and set methods you already wrote for points. Add another property: Description = property(GetDescription,…

Please follow the steps to complete JAVA PROGRAM Create a class, EmployeeException, that has the following attributes: name: String SSN: String Salary: double The methods required in this class are: A constructor with no arguments that sets the attributes at default values A constructor that passes values for all attributes Accessor, mutator, display method for each attribute. An example of a display method for an attribute is writeOutName(): void, in which you just display the name:System.out.println("Employee Name: " + name); An equals method that has an object of type Employee as argument, and returns true if two employees have the same name, salary, and SSN. Write a driver program for the Employee class that uses an array that can hold up to 100 employees (the array will be of EmployeeException type). However, the user should be free to enter as many employees as needed. The driver class should use two exception classes to signal the user that the SSN entered is not correct.…

Game class instructions:• Game class has three attributes: points (which represent the number of points awarded when winning the game), status (false if the game has not been played and true if the game has been played), and description (which is a text description of the game). Note that description attribute is a read-only variable. • In the constructor, initialize points to zero, status to false, and description to the given parameter.• isPlayed method returns true if the game has been played, and false otherwise.• getPoints is a getter method for points attribute.• play method is an abstract method.• Override toString method to return the game description.• Override equals method so that two games are the same if their descriptions are the same. :instructions class ) HangMan• HangMan is a game in which a player tries to guess a word based on a given hint.
