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 parameters. These values should be assigned to the object’s yearand make fields. The constructor should also assign 0 to the speed field. Accessors: design appropriate accessor methods to get the values stored in an object’s year, 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.
