1. (70 points) OOP related.

Write a class named Car that has the following data attributes:

• year (for the car’s year model)

• make (for the make of the car)

• speed (for the car’s current speed). Speed should be private.

The Car class should have following methods:

• __init__ method

• Setters and getters methods

• Display method that will display the information of the car.

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.

Next, design a program (main) that creates two objects of a Car class then calls the

accelerate and brake methods for the two objects. After that call the display method for the

two objects.
