Car class

Create a Car class using the following specifications (HINT: Use your Person class as a template):

BE SURE TO COMMENT YOUR CODE


Attributes (private):

  • color (default: "no color")
  • year (default: 0)
  • make (default: "no make")
  • model (default: "no model")
  • speed (default: 0)
  • gear (default: "no gear")


Methods (public)

  • default constructor (sets all attributes to their defaults)
  • setters (mutators) for all attributes
  • getters (accessors) for all attributes
  • String toString()
  • void park()
    • sets the current speed to 0 and the current gear to "P"
  • void drive(int newSpeed)
    • sets the current gear to "D" and changes the current speed to the newSpeed

CarTestMain:

Use the following code to test your Car class:

public class CarTestMain
{
  public static void main(String [] args)
  {
    //use the default constructor to create a new instance of Car
    Car myCar = new Car();

    //testing all getters (accessors)
    System.out.println("myCar.getColor(): " + myCar.getColor());
    System.out.println("myCar.getYear(): " + myCar.getYear());
    System.out.println("myCar.getMake(): " + myCar.getMake());
    System.out.println("myCar.getModel(): " + myCar.getModel());
    System.out.println("myCar.getSpeed(): " + myCar.getSpeed());
    System.out.println("myCar.getGear(): " + myCar.getGear());

    //testing all setters (mutators)
    myCar.setColor("green");
    myCar.setYear(2001);
    myCar.setMake("Isuzu");
    myCar.setModel("Rodeo");
    myCar.setSpeed(55);
    myCar.setGear("D");

    System.out.println("myCar.getColor(): " + myCar.getColor());
    System.out.println("myCar.getYear(): " + myCar.getYear());
    System.out.println("myCar.getMake(): " + myCar.getMake());
    System.out.println("myCar.getModel(): " + myCar.getModel());
    System.out.println("myCar.getSpeed(): " + myCar.getSpeed());
    System.out.println("myCar.getGear(): " + myCar.getGear());

    //test drive()
    myCar.drive(88);

    //test toString()
    System.out.println(myCar);

    //test park()
    myCar.park();
    System.out.println(myCar);
  }
}
