Assignment # 5 –

Design and implement a class called MonetaryCoin that is derived from the Coin class below. MonetaryCoin should inherit its parent’s ability to be “flipped.”

MonetaryCoin should

· extend Coin

· store an integer value when constructed (either 1, 5, 10, 25, 50, 100, 500 or 1000).

· have a getValue() method that returns its integer value.

· implement the Comparable interface

· override the toString()method to return its value.

MonetaryCoin value of:	toString( ) should return:
1	penny
5	nickel
10	dime
25	quarter
50	half dollar
100	dollar
500	five dollars
1000	ten dollars

Use the Main class to drive MonetaryClass.

import java.util.*;

public class Main {

public static void main(String [] args) {

Random gen = new Random();

int [ ] value = { 1, 5, 10, 25, 50, 100, 500, 1000};

int x, i;

MonetaryCoin [] coins = new MonetaryCoin[10];

for (i = 0; i < coins.length; i++) {

x = Math.abs(gen.nextInt()) % value.length;

coins [i] = new MonetaryCoin(value[x]);

}

System.out.println("Before the coins are sorted:");

for (i = 0; i < coins.length; i++)

System.out.println("\t" + coins [i]);

System.out.println("\nAfter the coins are sorted:");

Arrays.sort(coins);

for (i = 0; i < coins.length; i++)

System.out.println("\t" + coins [i]);

System.out.println("\n" + coins[0]

+ " before flipping is "

+ coins[0].getFace()

+ " after flipping is "

+ coins[0].flip());

}

The Coin class.

import java.util.*;

public class Coin {

private Random gen = new Random();

private final int HEADS = 0;

private int face;

public Coin () {

flip();

}

public String flip () {

face = (int) (Math.abs(gen.nextInt()) % 2);

return getFace();

}

public String getFace(){

String faceName;

if (face == HEADS)

faceName = "Heads";

else

faceName = "Tails";

return faceName;

}

public String toString() {

return getFace();

}

Do not make any modifications to the Coin class or to the Main class.

Create a MonetaryCoin class

Test your program for correctness and accuracy, prior to submitting it for grading.

Compare your program to the Program Deduction Check List to avoid penalty points.

If the program works correctly, the output will appear similar to the following:

Before the coins are sorted:

nickel

dollar

dime

penny

dollar

five dollars

dime

ten dollars

After the coins are sorted:

penny

nickel

dime

dollar

five dollars

ten dollars

penny before flipping is Tails after flipping is Tails
