Write a class named Car that has the following member variables: yearModel: An int that holds the car’s year model. name: A string that holds the name of the car. company: A string that holds the company of the car. speed: An int that holds the car’s current speed. In addition, the class should have the following member functions. Mutator: Appropriate accessor functions to set the values of object’s yearModel, name, company, and speed member variables. Accessor: Appropriate accessor functions to get the values stored in an object’s yearModel, company, and speed member variables. Accelerate: The accelerate function should add 5 to the speed member variable each time it is called. Brake: The brake function should subtract 5 from the speed member variable each time it is called. Demonstrate the class in a program that creates a Car object, call the setter functions to set the values and then call the accelerate function five times. After each call to the accelerate function, get...

QUESTION 24 If an array is declared at the class level, a. the array must also be created at the class level for the class methods to use it b. the size of the array is determined at the class level C. the array is available to some of the class methods but not all d. the array is created at the method level when the size is determined 2 p

In Python For problems A, B, and C you will be writing two different classes to simulate a Boat race. Problem A is to write the first class Boat. A Boat object must hold the following information boat_name: string top_speed: int current_progress: int Write a constructor that allows the programmer to create an object of type Boat with the arguments boat_name and top_speed. The boat_name should be set to the value of the corresponding argument - this argument is required. The top_speed should default to the value 3 if no value is passed in for the argument. The value for current_progress should always be set to 0. Implement Boat class with setter and getter methods: Provide setters for the following instance variables: set_top_speed takes in an int and updates the top_speed set_boat_name takes in a string and updates the boat_name set_current_progress takes in a int and updates the current_progress Provide getters for the following instance variables with no input parameters...

Design a class named StopWatch. The class contains:■しかく■しかく Private data fields startTime and endTime with getter methods.■しかく■しかく A no-arg constructor that initializes startTime with the current time.■しかく■しかく A method named start() that resets the startTime to the current time.■しかく■しかく A method named stop() that sets the endTime to the current time.■しかく■しかく A method named getElapsedTime() that returns the elapsed time for thestopwatch in milliseconds.Draw the UML diagram for the class then implement the class. Write a test programthat measures the execution time of sorting 100,000 numbers using selection sort.

PYTHON: Define the Artist class with a constructor to initialize an artist's information and a print_info() method. The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. print_info() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise. Define the Artwork class with a constructor to initialize an artwork's information and a print_info() method. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Ex: If the input is: Pablo Picasso 1881 1973 Three Musicians 1921 the output is: Artist: Pablo Picasso (1881-1973) Title: Three Musicians, 1921 If the input is: Brice Marden 1938 -1 Distant Muses 2000 the output is: Artist: Brice Marden, born 1938 Title: Distant Muses, 2000 I have the code but I am getting errors that I can't seem to get rid of any suggestions would be appreciated

Code the StudentAccount class according to the class diagramMethods explanation:pay(double): doubleThis method is called when a student pays an amount towards outstanding fees. The balance isreduced by the amount received. The updated balance is returned by the method.addFees(double): doubleThis method is called to increase the balance by the amount received as a parameter. The updatedbalance is returned by the method.refund(): voidThis method is called when any monies owned to the student is paid out. This method can onlyrefund a student if the balance is negative. It displays the amount to be refunded and set thebalance to zero. (Use Math.abs(double) in your output message). If there is no refund, display anappropriate message.Test your StudentAccount class by creating objects and calling the methods addFees(), pay() andrefund(). Use toString() to display the object’s data after each method called

Design/code/test a Java program containing an abstract the class absWelcome. This class should contain: 1. A public abstract void method (you name it) that is empty 2. A public regular method (you name it) that prints "Welcome to " Next, create a subclass clsHello that extends absWelcome. This class should contain: • A public regular method (you name it) that prints "Java Programming" Finally, inside the Main class create an object (you name it) from the clsHello class. Use this new object reference to: 1. Output "Welcome to " from the abstract class 2. Output "Java Programming" from the subclass Your output should resemble that shown below>sh -c javac -classpath -type f-name '*.java') java -classpath :targe Welcome to Java Programming
