- {In Java Programming Please} Create a class hierarchy that represents different types of employees in a company. Start with a class called Employee that has two methods: calculateSalary() and displayDetails(). Then, create two subclasses of Employee: Manager and Engineer. Override the calculateSalary() method in both subclasses to calculate the salary based on their job role and experience. Override the displayDetails() method in both subclasses to print out a message indicating the details of the employee. Next, create another class called Salesperson that extends Employee and has a method called calculateCommission(). Create two subclasses of Salesperson: SeniorSalesperson and JuniorSalesperson. Override the calculateCommission() method in both subclasses to calculate the commission based on their sales performance. Override the displayDetails() method in both subclasses to print out a message indicating the details of the salesperson. In the main method, create objects of each class…Please with interface Write a program in Java for the university consisting of the following categories: A mere Person classification contains the following variables:String name The person's name. 1int id id number. 2Write a constructor that receives the variables and a function (ID int , name String(add) whereYou receive the person's name and ID number and assign them.

- About the Java programming paradigm/style, mark the most correct alternative: 1. Java is object-oriented and this is the only supported programming paradigm/style. B. Java is mostly object-oriented, however, it is possible to do structured programming (albeit within the main method) and there are some functional aspects, such as lambdas. Ç. Java is mostly object-oriented, that is, it is possible to do structured programming exclusively within the main method. D. Java is a language for structured programming, however it is possible to do object orientation. AND. Java is a language for structured programming, however it is possible to be object oriented, but not functional.What key word is used to define a subclass from a super class?

- Write a code in Java programming You are working in a game company that is developing a new RPG game. One of the core features of the game is the ability to create and manage different types of characters, such as warriors, mages, and archers. However, your colleague, who was previously working on the implementation of the CharacterManager class, has been laid off due to excessive absences. You have been assigned to take over the project and complete the implementation of the class based on the design specifications outlined below: Given the following main method: public static void main(String[] args) { CharacterManager manager = CharacterManager.getInstance(); manager.createCharacter(CharacterType.WARRIOR).attack(); manager.createCharacter(CharacterType.MAGE).attack(); manager.createCharacter(CharacterType.ARCHER).attack(); } Your output should be: Warrior is attacking Mage is attacking Archer is attacking Note that you should not change the method signature.Create a Java program that has the following: Inheritance - Create a superclass and one or more subclasses that inherit properties and methods from the superclass. Polymorphism - Show polymorphism by using method overriding and method overloading. Provide an example of runtime polymorphism by creating objects of the subclasses and calling overridden methods. Encapsulation - Demonstrate the concept of encapsulation by applying access modifiers (private, protected, public) appropriately in your program. Abstraction - Utilize abstract classes and methods in your program to illustrate abstraction. Show examples of the following words: super, this, static, finalWrite a complete Java class that can be used to create a Fish object as described below: A Fish has-a: - name age - type favorite food a) Add all instance variables b) The class must have getters and setters for all instance variables c) The class must have two constructors: a no-args constructor and a constructor that receives all data fields as parameters d) The class must have a toString() e) Add a main method and create 2 Fishes using each of the constructors you created
- Inheritance and polmorphism: In Java, Using Classes, desine an online address book to keep track of the names , addresses phone numbers, and birthdays of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. A. Define the class Address that can store a street address, city, state, and zip code. Use the appropriae methods to print and store the address. Also, use consructors to automatically initialize the data members. B. Define the class ExtPerson using the class Person (designed in chapter 8, example 8-8), the class Date, and the class Address. Add a data member to the class to claddify the person as a family member, friend, or business associate. Also, add a data member to store the phone number. Add (or override) methods to print and store the appropriate informatiom. Use constructors to automatically omotoa;ize the data members. C. Define the class AddressBook using previously defined classes. An object of…Python programming Implement a constructor for the Person class Implement a constructor for the Student class Create a student with name; Albert Einstein, ramq: 14031879-1235, address: 112 Mercer Street, Princeton, courses: (1)Physics & (2)Relativity where the grades were b and a respectively and with enrollment date: 1895Design/code/test a Java program containing an abstract the class absWelcome. This class should contain: 1. A public abstract void method (you name it) that is empty 2. A public regular method (you name it) that prints "Welcome to " Next, create a subclass clsHello that extends absWelcome. This class should contain: • A public regular method (you name it) that prints "Java Programming" Finally, inside the Main class create an object (you name it) from the clsHello class. Use this new object reference to: 1. Output "Welcome to " from the abstract class 2. Output "Java Programming" from the subclass Your output should resemble that shown below >sh -c javac -classpath -type f-name '*.java') java -classpath :targe Welcome to Java Programming
