3. The interface Range is defined below:public interface Range{ void setLimits(int x, int y); int getNumber();} Implementations of Range should exhibit the following behaviour:• The setLimits method should store its parameter values somewhere to serve as the lower and upper limits of the range appropriately.• A call to getValue should return an integer that is always greater than or equal to the lower limit and less than or equal to the upper limit.The class RandomInteger is an implementation of the interface Range. It also has the following features:• It has two fields of int type, low and high, to record the lower and upper limits of the range, respectively.• It has single constructor method that takes two integers and stores them in the appropriate fields. Note: You should make use of the setLimits method.• A call to the method getNumber should return a random number that is always within the range, i.e. greater than or equal to the lower limit and less than or equal to the upper…
Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of an empty box, return null. Write a main method that tests your class.
Write a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class. Show the use of constructor from parent class (mind you, RemoteStudents have one additional parameter – discussion). Implement the abstract method score() of the parent class to calculate the weighted score for both types of students. Write a driver class JavaProgramming.java which has the main method. Create one remote student object and one in-person student object. The output should show prompts to enter individual scores – midterm, finals, ...... etc. and the program will…
1 - Student class Make a class student (in student.py) that stores the following information for a student: Name (name) Student number (student_nr) Points per assignment (points_per_assignment) Exam grade (exam_grade) a) Behind each point of information is the name of the parameter to the initializer method. Store this information from the parameters in the object attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is explained in the course overview, course setup slides (Links to an external site.) and the first lectureLinks to an external site.. c) Add a method grade() which returns a the final grade of the student, rounded to nearest half (upwards, 6.75 -> 7). As per regulations, a 5.5 becomes a 6. If the student did not pass both the assignments (>= 95…
Write a class definition line and a one line docstring for the class Dog. Write an __init__ method for the class Dog that gives each dog its own name and breed. Test this on a successful creation of a Dog object.>>> import dog>>> sugar = dog.Dog('Sugar', 'border collie')>>> sugar.name'Sugar'>>> sugar.breed'border collie' Add a data attribute tricks of type list to each Dog instance and initialize it in __init__ to the empty list. The user does not have to supply a list of tricks when constructing a Dog instance. Make sure that you test this successfully.>>> sugar.tricks[] Write a method teach as part of the class Dog. The method teach should add a passed string parameter to tricks and print a message that the dog knows the trick.>>> sugar.teach('frisbee')Sugar knows frisbee
Write a java program that Create a generic class AnimalList that has a type parameter T. It should have at least two properties declared as the passed type, constructors), getters, setters, and toString methods. Create a superclass Animal that has two properties (String, int, etc.), and constructor, getters, setters, and toString methods. Create two subclasses of Animal called Cat and Dog. Each class should have a unique property and method. Create a class Lizard with a method of your choice. Create a main class AnimalTest that creates two instances of Animal: Dog type and Cat type. Create a method that takes Animal type as parameter constraining the types to be subclasses of the Animal class only; check the type of object and call the unique method in the Dog and Cat. Create an instance of the Lizard class and test it. Display all objects.
Write an interface and then modify classes to implement the interface. Write an interface, GeometricSolid, which has one method, volume. The volume method takes no arguments and returns a double. You are provided with three classes: Cylinder, Sphere, and RightCircularCone Modify the classes so that they implement the GeometricSolid interface. Supply the appropriate method for each class. Make sure that you use Math.PI in your calculations. Notice in InterfaceRunner that the objects are added to an ArrayList of GeometricSolids. Cylinder.java /*** Models a Cylinder*/public class Cylinder {private double radius;private double height; /*** Constructor for objects of class Cylinder* @param radius the radius of the Cylinder* @param height the height of this Cylinder*/public Cylinder(double radius, double height){this.radius = radius;this.height = height;}/*** Gets the radius of this Cylinder* @return the radius of the Cylinder*/public double getRadius(){return radius;}/*** Sets the radius of…
The Java Programming class has two types – remote and in-person. For remote students, the weighted score comprises of midterm, final, assignments and discussion. The weights for each are 30%, 30%, 30% and 10% respectively. For in-person students, the weighted score comprises of midterm, final and assignments. The weights for each are 30%, 30% and 40%. Write a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class.

Write a class called Pokemon that has a name (e.g. “Pikachu”) and a number (e.g. 25). Implement a constructor that takes both values as parameters. Implement accessors for both values. Implement a toString() that returns a string in the format “Name(number)”, e.g. “Pikachu(25)”. Implement an equals(Object) method (two Pokémon are considered equal if they have the same number). Implement a hashCode() method that returns the number.(remember the equals and hashCode contract).
*using java* Create a class AnimalCreate a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal(String name) //constructor public void makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don’t make sounds!)Note, you’ll also need a constructor in each of your subclasses which calls super(name) to initialize the common ‘name’ member of Animal. --- Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. ( you should observe the implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…
Books can come in various formats, like paper books, audio books, ebooks, etc. Create a generic classBook that has as common attributes the title, the year of publication, and the author. The constructor of thisclass should instantiate all three attributes. Override the toString method of class Book that returns a stringthat contains the values of its attributes. Create a subclass PrintBook that extends Book with attributesPublisher and ISBN. Create another subclass AudioBook which has the book’s size (in MB), its playlength and the playback artist’s name as attributes. Both PrintBook and AudioBook classes override thetoString method inherited from Book. Write a Java application to demonstrate the usage of this hierarchy.
