Question

hey guys. I'm looking to get some help with this project. Please don't make the coding difficult to understand, I am trying to get a firmer grasp on this subject. Thank you. Write a class named Car that has the following fields: -yearModel. The yearModel field is an int that holds the car'syear model. -make. The make field references a String object that holdsthe make of the car. -speed. The speed field is an int that holds the car's currentspeed. In addition, the class should have the following constructorand other methods. -Constructor. The constructor should accept the car's yearmodel and make as arguments. These values should be assigned to theobject's yearModel and make fields. The constructor should alsoassign 0 to the speed field. -Accessors. Appropriate accessor methods should get the valuesstored in an object's yearModel, make, and speed fields. -accelerate. The accelerate method should add 5 to the speedfield each time it is called. -brake. The breake method should substract 5 from the speedfield each time it is called. Demonstrate the class in a program that creates a Car object,and then calls the accelerate method five times. After each call tothe accelerate method, get the current speed of the car and displayit. Then call the brake method five times. After each call to thebrake method, get the current speed of the car and displayit.

# declare a class class Bird: """ This Bird class represents a Bird, it has a name, a color, a size, and an x,y,z position. This is a doc string for the class. It's always good to include doc strings for classes and class methods. """ def __init__(self, name, color, size): """ This __init__ method is called when an instance of a Bird is constructed.
