The Parrot class represents a parrot with an age in years and the ability to learn sounds which can repeat back when asked to speak. The declaration of the Parrot class is shown below.

public class Parrot

{

//creates a new Parrot object

public Parrot(String name)

{

//implementation not shown

}

//returns the age of the parrot

public int getAge()

{

//implementation not shown

} //adds a sound to the list of sounds the parrot can make

public void train(String sound)

{

//implementation not shown

}

public String speak()

{

//implementation not shown

}

A pirate parrot is a type of parrot. A pirate parrot knows how to make the sound Polly want a cracker immediately upon birth. A pirate parrot can also steal souls whose age becomes part of the pirate parrots age. A pirate parrot is represented by the PirateParrot class, which you will write.

Assume that the following code segment appears in a class other than PirateParrot. The code segment shows an example of using the PirateParrot class.

PirateParrot polly = new PirateParrot(Polly);

System.out.println(polly.getAge()); //prints 0

// code to increase Pollys age by 5 years

System.out.println(polly.getAge()); //prints 5

polly.stealSoul(5);

polly.stealSoul(10);

System.out.println(polly.getAge()); //prints 20

polly.train(Walk the plank);

polly.train(Off with his head);

//Polly retires from his life as a pirate to a cushy life as a pet

Parrot myPetPolly = polly;

System.out.println(myPetPolly.getAge()); //prints 20

myPetPolly.train(Time for bed);

System.out.println(myPetPolly.speak());

/* prints one of the following at random

* Polly wants a cracker

* Walk the plank

* Off with his head

* Time for bed

*/

Write the PirateParrot class. Your code must produce the indicated results.
