This exercise demonstrates using a reference parameter to pass data back to the calling method. Suppose you want a

Car5

class to include a method with this heading:

public boolean copyTo(Car5 newCar)

This method is supposed to be called by an existing

Car5

object with another

Car5

object as the argument. If any of the calling car’s instance variables has not been initialized, the desired method should not try to modify any of the new car’s instance variable values, and the method should return

false.

Otherwise, the method should copy all of the calling car’s instance variable values into the new car and return

true.

Here’s a driver that illustrates the usage:

/***************************************************************** Car5Driver.java* Dean&Dean** This class is a demonstration driver for the Car5 class.****************************************************************/public class Car5Driver{      public static void main(String[] args)      {           Car5 silviaCar = new Car5();           Car5 jayCar = new Car5();           System.out.println(silviaCar.copyTo(jayCar));           silviaCar = new Car5("Fiat", 2015, "black");           System.out.println(silviaCar.copyTo(jayCar));      } // end main} // end class Car5Driver

Output:

falsetrue

Write the code for the desired

copyTo

method.
