Chapter 10.2, Problem 10.5CP

Look at the following classes:

 public class Ground

 {

  public Ground()

  {

    System.out.println(“You are on the ground.”);

   }

   public Ground(String groundColor)

  {

    System.out.println(“The ground is ” + groundColor);

  }

 }

 public class Sky extends Ground

 {

   public Sky()

   {

     System.out.println(“You are in the sky.”);

   }

   public Sky(String skyColor)

   {

   super(“green”);

   System.out.println(“The sky is “ + skyColor);

   }

  }

What will the following program display?

 public class Checkpoint

 {

  public static void main(String[] args)

  {

    Sky object = new Sky(“blue”);

  }

 }
