Employee Class
Write a class named Employee that has the following fields:
- name. The name field references a String object that holds the employee’s name.
- idNumber. The idNumber is an int variable that holds the employee’s ID number.
- department. The department field references a String object that holds the name of the department where the employee works.
- position. The position field references a String object that holds the employee’s job title.
The class should have the following constructors:
- A constructor that accepts the following values as arguments and assigns them to the appropriate fields: employee’s name, employee’s ID number, department, and position.
- A constructor that accepts the following values as arguments and assigns them to the appropriate fields: employee’s name and ID number. The department and position fields should be assigned an empty string (" "),
- A no-arg constructor that assigns empty strings (" ") to the name, department, and position fields, and 0 to the idNumber field.
Write appropriate mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have written the class, write a separate
The program should store this data in the three objects and then display the data for each employee on the screen.

Car Class Create a Python Program where you write a class named Car that has the following data attributes: • _ _year_model (for the car's year model) • __make (for the make of the car) • _ _speed (for the car's current speed) The Car class should have an _init_ method that accepts the car's year model and make as arguments. These values should be assigned to the object's _year_model and make data attributes. It should also assign 0 to the __speed data attribute. The class should also have the following methods: accelerate() The accelerate method should add 5 to the speed data attribute each time it is called. brake() The brake method should subtract 5 from the speed data attribute each time it is called. • get_speed() The get_speed method should return the current speed. Next, design a program that creates a Car object then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method…arrow_forwardCreate a class named Car that has the following properties: • Year—The Year property holds the car’s year model. • Make—The Make property holds the make of the car. • Speed—The Speed property holds the car’s current speed.

These values should be assigned to the backing fields for the object’s Year and Make properties. The constructor should also assign 0 to the backing field for the Speed property. • Accelerate—The Accelerate method should add 5 to the Speed property’s backing field each time it is called. • Brake—The Brake method should subtract 5 from the Speed property’s backing field each time it is called.

The data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…arrow_forward
