- Write a java program Write a class named Employee with name and salary as private data fields. Add a constructor with both parameters. Write a class named Manager which unherits the Employee class. Add an instance variable, named department, of type String and 15 private. Add a constructor in the subclass class and a toString () method that prints the manager's name, department, and salary [Hint: Add a tastanel) method in the super class as well]. Create objects of Manager and Employee dassUsing any application of your choice, write a Java program that meets the following requirements: It has an abstract class that contains a student number; Include get() and set() methods for the abstract class where the student number is set/get; Create three child classes, for firstYear, secondYear and thirdYear. Each class must display a distinct announcement for first years, second years and third years.Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format. Student number PMark EMark MMark Mar#9186 81 64 72.00 1.2 Create a testStudents class. Do the following: -Write a static method called display() which receives…
- Write a program in java Design a class that holds the following personal data: name, address, age, and phone number.Write appropriate accessor and mutator methods. Demonstrate the class by writing aprogram that creates three instances of it. One instance should hold your information, andthe other two should hold your friends’ or family members’ information.write a java program A course has a name, a course number, a department code(for example, CS, MATH) and a room number.• Include a static variable used to assign the course number to each Course in theconstructor. The value of the variable will start at 1000.• Write the instance variables, the accessors (getters), the mutators (setters) and twoconstructors for the class. One of the constructors should be the no args constructorWrite a second class, XXX_ TestCourse (XXX is your Kean Id) ,which will have amain method.• Create an Array of Course objects, which can hold 3 elements.• Using a loop:• Ask the user for the name, department and room number for 3 courses.• Create course objects.• Store the objects in the Array• At the end, traverse the array of courses and print each course on a separate lineImplement the following using JAVA: a.Design a class named Person and its two subclasses named Student andEmployee. b.Make Faculty and Staff subclasses of Employee. Please note that,● A person has a name, address, phone number, and email address. A student has aclass status (freshman,sophomore, junior, or senior). You can define the status as aconstant.● An employee has office & salary.● A faculty member has office hours and a rank.● A staff member has a title. c. Draw a UML diagram of the system.

Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer numberand a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Demonstrate an instance of the Customer class in a simple program.Write the implementation of the Java classes based on the following UML diagram. (a) Define the method IncreTotSpecies) to increment the data field totalSpecles (b) Define the method printColor) to print the data field color (c) Override the method printColor) in the class Falcon to print the data fields featherColor, beakColor Birds +color: String +foodHabit: String +totalSpecies: int -skeleton: String +Birds () +Birds(color: String, foodHabit: String, skeleton: String) +increTotSpecies (): void +printColor (): void Falcon -featherColor: String -beakColor: String +Falcon (featherColor: String, beakColor: String) +printColor (): void
- Write a class named Person with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the Customer class in a simple program. All your programs will be modular. It will have the main() method that is executed first. Submit code that has no syntax error. And test your code, so as to not have logic errors. Each program must contain your name in the comments section and the date you created the code.Your assignment for this course is to implement a beginner level Book Management System (BMS) in Java language. BMS contains 2 classes: Bookand BookList. The Book class has the following attributes: code: a String object, that hold the book’s code. title: a String object, that hold the book’s title. qua: int variable, that hold the number of books with the same code in the library. price: a double variable, that hold the book’s price. The BookList class contains only one data member: ArrayList<Book> t. When running the program display the menu as below:1. Input & add book(s) to the end.2. Display all books.3. Search a book for given code.4. Update the book’s price for given code.5. Find the (first) max price value.6. Sort the list ascendingly by code.7. Remove the book having given code.8. Load data from file.0. Exit.Notes:(1) The book’s code must be unique in the list.(2) Display all books in format (code, title, quantity, price).(5)…Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle.
