Define a class named UnfairCandyDistributor. An UnfairCandyDistributor object represents a mean big brother who is going to divide a set of candies between himself and his hungry little brother. This will be done unfairly: for every candy given to the sibling, the big brother takes for himself a number of additional candies equal to the younger sibling's total. Each UnfairCandyDistributor object should have the same method: public void nextCandy () Each time nextCandy is called, the method prints a message about who gets a candy. Each call to nextCandy produces a single line of output. This time the output is the following:

Define a class named CandyDistributor. A CandyDistributor object represents a hungry child who is going to divide a set of candies between herself and her hungry sibling. This will be done fairly by alternating who gets a candy. Each CandyDistributor object should have the following method: public void nextCandy() Each time nextCandy is called, the method prints a message about who gets a candy, and how many candies that person has. Each call to nextCandy produces a single line of output. The code below constructs a CandyDistributor object and calls its nextCandy 8 times. The output appears at right. public class TestCandy { public static void main(String[] args) { CandyDistributor nice = new CandyDistributor(); nice.nextCandy(); // 1 for you. nice.nextCandy(); // 1 for me. nice.nextCandy(); // 2 for you. nice.nextCandy(); // 2 for me. nice.nextCandy(); // 3 for you. nice.nextCandy();…
1. Define a class named Randomwalker. A Randomwalker object should keep track of its (x, y) location. All walkers start at the coordinates (0, 0). When a walker is asked to move, it randomly moves either left, right, up or down. Each of these four moves should occur with equal probability. The resulting behavior is known as a "random walk." (A 2-dimensional random walk example is pictured at right.) Each Randomwal ker object should have the following public methods. You may add whatever fields or methods you feel are necessary to implement these methods: move () Instructs this random walker to randomly make one of the 4 possible moves (up, down, left, or right). getX () Returns this random walker's current x-coordinate. getY () Returns this random walker's current y-coordinate. getsters () Returns the number of steps this random walker has taken.
Define a class Student to create Student Objects. The class defines two variables for its objects: name (String ) and average (double). The class provides a constructor with arguments and includes the following object methods to do the following: - public void print() : prints the Student data - public void setAverage(double newAvergae): sets the student average with a new value. Define a class StudentTest In the main method, create three student objects (Ali, Rami, Khalid) with initial average 60 for each one. - Call the setAverage method on each created student to change their average with a randomly value (hint: use Math.random( ) method to generate average value in range [0..100]). - Print the name of the student who's the maximum average. hint: you should compare between the Student objects according to their average.
Create a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…
Design and implement a class called Car that contains instance data that represents the make, model, and year of the car (as a String, String and int value respectively). Define the Car constructor to initialize these values (in that order). Include getter and setter methods for all instance data, and a toString method that returns a one-line description of the car of the form make-model (year)for example:Ford-Thunderbird (1955)
Design a class Parallelogram that contains two private data members: - double length, - double height. Parallelogram class should also have following public methods: - parameterized constructor, - a method to calculate area of parallelogram. Design another class Rectangle that inherits from Parallelogram (since a Rectangle is-a Parallelogram). Class Rectangle should have the following public members: - parameterized constructor, - a method to calculate perimeter, - a method to tell if the Rectangle object is a Square. Develop the main function to fully test these two classes. Note: 1. please use multiple files (separate compilation) 2. length and height should be protected members in the base class, as you need them to calculate perimeter of a rectangle.
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…
1. Design a new Triangle class that extends the abstract GeometricObject class. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.
Design a class that holds the following personal data:name, address, age, and phone numbers. Writeappropriate accessor, mutator methods. Demonstrate theclass by writing a program that creates three instances ofit. One instance should hold you’re your information, andthe other two should hold your friends’ or familymembers’ information.
1- Create a hierarchy of Java classes as follows: MyRectangle is_a MyShape; MyOval is a MyShape. Class MyPoint: Class MyPoint is used by class MyShape to define the reference point, p(x, y), of the Java display coordinate system, as well as by all subclasses in the class hierarchy to define the points stipulated in the subclass definition. The class utilizes a color of enum reference type MyColor, and includes appropriate class constructors and methods. The class also includes draw and toString methods, as well as methods that perform point related operations, including but not limited to, shift of point position, distance to the origin and to another point, angle [in degrees] with the x-axis of the line extending from this point to another point. Enum MyColor: Enum MyColor is used by class MyShape and all subclasses in the class hierarchy to define the colors of the shapes. The enum reference type defines a set of constant colors by their red, green, blue, and opacity, components,…
