Create a project consisting of three classes. These three classes are named ProgTwo.java, Product.java and ProductCollection.java. You must have these three classes and they must work as it is described in these specifications. You are welcome to add methods to any class that you may find useful. You must add comments to all your classes, using the javadoc style commenting modeled in class. You may add other classes if you consider them necessary.

Debug this code below $($ProductCollection$.$java$)$:

class ProductCollection$\{$

public Product$[]$ collection;

public int count;

int maximumSize;

public ProductCollection$()$

$\{$

maximumSize$=20$;

collection$=$new Product$[$maximumSize$]$;

count$=0$;

$\}$

public void addProduct$($int prodID,String prodName, double unitPrice,int prodQty$)$

$\{$

if$($count
