Write an abstract class FacultyAbstract which has abstract methods ,void setDetails (String name, double basic_sal, double allowance) ,getDetails() and getSalary(double basic_sal, double allowance) ,Create another class Lecturer which extends the FacultyAbstract class and defines the above methods in this class setDetails (String name,double basic_sal, double allowance) asks the user to enter the details of the lecturer like name, basic salary and allowance .getDetails() displays, name, basic salary and allowance of a lecturer .getSalary(double basic_sal, double allowance) returns the total salary of the lecturer .Create an object obj of Lecturer class, ask the user to enter the values, and then call the getmethods .Mention your final output

1. Create a Student class that implements the Person interface. As well as storing the students name and email, also store their course grade (e.g A, B, C) in a member variable. The grade should be accessible via a getGrade method. For the implementation of getDescription return a message along the lines of “A C grade student”, substituting the students actual grade.2. Create a Lecturer class that implements the Person interface. This class should also store the subject that the lecturer teaches. Add a getSubject method, and implement getDescription so that it returns a suitable message, e.g. “Teaches Biology”.3. Create a third class, Employee that implements the interface. This should also store the name of the department the Employee works in (available via getDepartment). Again, getDescription should return a suitable message.

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…

Java Program   The assignment requires two classes. Put all classes in the same package. Class Employee Attributes (all private): id: String lastName: String firstName: String salary: int Methods: Parameterized constructor for initializing a new Employee instance Getters for all attributes toString method to display an Employee's attributes (See output of executable below)  Executable Class Create an array of at least eight Employee objects. Be sure to use many with identical last names, but don't order them by name in the array.  Create an ArrayList from the array. Sort the ArrayList first by last name and then by first name.  Using the forEach method and a lambda expression, print all employees alphabetically sorted by name. Create a LinkedList from the ArrayList. Create an iterator capable of cycling both forward and backward through the LinkedList. Iterate forward through the LinkedList without generating any output. Then iterate backwards through the LinkedList to print…

Design a console program that will print details of prescribed textbooks of students. Make use of an abstract class Book with variables that will store the author, title, category and price of a book. Create a constructor that accepts the author, title and category through parameters and assign these to the class variables. Create an abstract set method for the price of a book; also create get methods for the variables.Create a subclass TextBook that extends the Book class and implements an iPrintable interface. The interface that must be added is shown below:public interface iPrintable { String DisplayDetails();}The TextBook subclass has a private variable named yearPrescribed for which a get method must be written. The constructor of the TextBook class must accept the author, title, category and yearPrescribed through parameters. Write the code for the setPrice() and DisplayDetails() methods.Write a useBook class and instantiate 2 objects of the TextBook class.

It has just one Main class which tests abstract class Animal and its 3 subclasses: Dog, Cat, and Fish. It also tests the Talkers: Dog, Cat, and Radio.  So your job is to write all 6 of these simple classes (they should be less than one page each) : Talker.java - the interface Talker, which has just one void method called speak() Animal.java - the abstract class Animal, which stores an animal's name. (No abstract methods). It should contain 2 methods: a constructor with 1 argument (the name) a method getName() which returns the name. Dog.java - the class Dog, which extends Animal and implements Talker.  It should contain 3 methods: a constructor with no arguments, giving the dog a default name of "Fido" a constructor with 1 argument (the name) a speak() method that prints "Woof" on the screen. Use @Override Cat.java - the class Cat,  which extends Animal and implements Talker.  It should contain just 2 methods: a constructor with 1 argument (the name)  (no default name like dogs…

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

This question involves the design of a class that will be used to produce practice problems. The following StudyPracticeinterface represents practice problems that can be used to study some subject.   public interface StudyPractice. { /**Returns the current practive problem */ String getProblem();   /** Changes to the next practice problem */ void nextProblem(); }   The MultPractice class is a StudyPracticethat produces multiplication practice problems. A MultPractice object is constructed with two integer values: first integer and initial second integer. The first integer is a value that remains constant and is used as the first integer in every practice problem. The initial second integer is used as the starting value for the second integer in the practice problems. This second value is incremented for each additional practice problem that is produced by the class. For example, a MultPractice object created with the call new MultPractice (7, 3)would be used to create the practice…
