Car Class
Write a class named Car that has the following fields:
- yearModel. The yearModel field is an int that holds the car’s year model.
- make. The make field references a String object that holds the make of the car.
- speed. The speed field is an int that holds the car’s current speed.
In addition, the class should have the following constructor and other methods.
- Constructor. The constructor should accept the car’s year model and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field.
- Accessors. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and speed fields.
- accelerate. The accelerate method should add 5 to the speed field each time it is called.
- brake. The brake method should subtract 5 from the speed field each time it is called.
