Class and Objects
1. Create a new Java class named Car that has the following fields
o year – The year field is an int that holds a car’s year model (e.g. 2010)
o make – The make field is a String object that holds the make of the car (e.g. “Porsche”) o speed – The speed field is an double that holds a car’s current speed (e.g. 25.0)
2. In addition, the Car class should have the following methods.
o Constructor – The constructor should accept the car’s year, make, and beginning speed as
arguments
These values should be used to initialize the Car’s year, make, and speed fields§
o Getter Methods – Write three accessor (getter) methods to get the getYear(), getMake(), getSpeed()§values stored in an object’s fields
o accelerate – Write an accelerate method that has no arguments (parameters) passed to it and adds 1 to the speed field each time it is called
For example: if the car was going 3 mph, accelerate would set the speed to 4 mph§
3. Write a separate Java class RaceTrack in file RaceTrack.java with a main method that uses
your Car class
Save the class in file RaceTrack.java in the same java project folder.
4. Inside RaceTrack class’ main method
o Create a new Car object (using the Car constructor method), passing in the year, make, and speed o Display the current status of the car object using the getter methods getYear(), getMake(),
and getSpeed()
o Call the car’s accelerate method and then re-display the car’s speed using getSpeed()
