For this assignment, create a child class of car that creates a car of a randomly generated color. Using the existing car classes, add code to add 20 colored cars to the existing pane in 20 visible, random locations. You will end up with 4 classes: CarViewer.java CarComponent.java Car.java (unchanged from Chapter 3) ColorCar.java (extends Car)

Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram {    public static void main (String [] args) {       Course course = new Course();            // Example students for testing      course.addStudent(new Student("Henry", "Bendel", 3.6));         course.addStudent(new Student("Johnny", "Min", 2.9));              System.out.println("Course size: " + course.courseSize());    } }   public class Student {     private String first;  // first name    private String last;   // last name    private…

The goal of this coding exercise is to create two classes BookstoreBook and LibraryBook. Both classes have these attributes: author: Stringtiltle: Stringisbn : String- The BookstoreBook has an additional data member to store the price of the book, and whether the book is on sale or not. If a bookstore book is on sale, we need to add the reduction percentage (like 20% off...etc). For a LibraryBook, we add the call number (that tells you where the book is in the library) as a string. The call number is automatically generated by the following procedure:The call number is a string with the format xx.yyy.c, where xx is the floor number that is randomly assigned (our library has 99 floors), yyy are the first three letters of the author’s name (we assume that all names are at least three letters long), and c is the last character of the isbn.- In each of the classes, add the setters, the getters, at least three constructors (of your choosing) and override the toString method (see samplerun…

USING JAVA: Part A) Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An Appointment has a description (for example, “See the dentist”) and a date. Write a method,                                           occuresOn(int year, int month, int day) The check whether the appointment occurs on that date. For example, for appointment, you must check whether the day of the month matches. This fill an array of Appointment objects with a mixture of appointments. Have the user enter a date and print out all appointments that occur on that date. Part B) Improve the appointment book by giving the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.

java please dont take other website'answer. rthis is actually practice question ANIMALCLASS Create an Animal class. Each animal has a name, an x and y integer coordinate. The Animal class should have at minimum the following methodsbelowbut you may want to add more if necessary: Also note, everyanimal will need to have to have “z”passed to it so that it knows how big the map is. •A constructor that starts the animal at 0,0 with a name of "Unknown Animal"and only accepts a single int value (int mapSize). •A parameter constructor that allows the programmerto input all 4pieces of information.(x,y, name, mapSize)oCheck the parameters for valid input based on the constraints. Ifany of the input valuesis invalid, adjust it any way you deem necessary in order to make it valid. •getX()and getY() •getName() •toString().  o This should print out the name and coordinates of the animal. •touching(Animal x) This method should determine if the animal is on the same spot as a secondanimal(x). It…

Can each class be done please I am not sure how to do each one. In java Make a program with classes named Vehicle, LandVehicle, AirVehicle, Car, Truck, Glider, Balloon, VehicleFactoryMain, MyFileManager. The Vehicle Inheritance looks like this: Note: Vehicle should also have a range.   Make sure to override the toString() method for returning a String that includes all the information about an instance of a vehicle.   VehicleFactoryMain will use these classes to make a random number and assortment of vehicle types. For example: Car - red, 526Km,1524Kg, 1988Kg, 1001Kg, gas, 4-wheels, 2-doors, fastback. Balloon - orange, 234Km,320Kg, 423Kg, 256Kg, gas,  950m, hot air.   For the various ranges, altitudes, and weights set a max and min value and randomly choose between those. For values that have types (hot-air, hydrogen, helium or gas, electric, diesel, kerosene, methane,none) make a static array in the class and randomly choose one of the values. Have the factory select a random number…

Java: According to this diagram, what are the methods that the StagBeetle class can use? (Select all that apply) Group of answer choices:    A: hornSize B: fly() C: emitPheromone() D: eat()

In this question, we will bake a class. Create a class Cake , with the following instance attributes: • name (a string) • ingreds (a list of strings) • price (a float) The Cake class has also the following methods: • Write a constructor that takes as input a string indicating the cake name, and a list of strings indicating the cake ingredients. (No docstring needed.) The constructor uses these values to initialize the attributes accordingly. Note that each cake should be assigned a random price between $10.00 (inclusive) and $15.00 (exclusive). You may import random . Moreover, a cake must contain at least three or more ingredients. If this is not the case, the constructor should raise a ValueError . For this constructor, do not worry about making a copy of the input array. You can simply copy the reference received as input into the corresponding attribute. 1 • Write a method (including docstring) called __str__ which returns a string containing the name of the cake and its price…

Create a class Course, which has one field: String courseName   Create the constructor, accessor, and mutator for the class. Then, in the main method of this class, create an instance of the class with the name "CST1201".   Write an equivalent while statement to replace the following for statement   for (int i=2; i<100; i=i+2) {        System.out.println(i); }
