Write a class called MonetaryCoin that is derived from the Coin class presented in Chapter 5. Store an integer in the MonetaryCoin that represents its value and add a method that returns its value. Create a main driver class to instantiate and compute the sum of several MonetaryCoin objects. Demonstrate that a monetary coin inherits its parents ability to be flipped.

Below is the Coin Class from Chapter 5:

public class Coin { private final int HEADS = 0; private final int TAILS = 1; private int face; //----------------------------------------------------------------- // Sets up the coin by flipping it initially. //----------------------------------------------------------------- public Coin () { flip(); } //----------------------------------------------------------------- // Flips the coin by randomly choosing a face value. //----------------------------------------------------------------- public void flip () { face = (int) (Math.random() * 2); } //----------------------------------------------------------------- // Returns true if the current face of the coin is heads. //----------------------------------------------------------------- public boolean isHeads () { return (face == HEADS); } //----------------------------------------------------------------- // Returns the current face of the coin as a string. //----------------------------------------------------------------- public String toString() { String faceName; if (face == HEADS) faceName = "Heads"; else faceName = "Tails"; return faceName; } }
