Question
{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 and call their respective methods to demonstrate polymorphism.

- 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.

Your program should contain a minimum of three classes: Order Class Display Class Main Class Create a Order Class that uses a queue to hold the orders in the order they were taken. The queue should contain the customer last name, order number, and order total cost. Create a Display Class that will store a copy of the order queue in two arrays. Each array will contain the order list but one will be sorted by name and the other sorted by order number. When a order is taken and stored in the Order Class the program will update theDisplay Class arrays automatically sort them in descending order using quick sort and outputs the the contents to the console upon each entry of new data. Create a Main Class that will handle operator data input and when an order is added or removed, the program will update the Order Class and Display Class. The user will be presented a menu to add a order, remove a order and display…arrow_forward
