Problem with restock fee not reporting

[javauser215]

My program compiles and runs okay, but is not displaying my restocking fee and I am not sure why. Attached is my printout of how it displays.

//Product.java works with Inventory4.java file

import java.util.Scanner; // program uses class Scanner
public class Product4
{
    //Private Variables

    private String name;               //Product name
    private int identificationNumber;  //The product identification number
    private int unitsInStock;          //Number of units in stock
    private double unitPriceInDollars; //The price of each unit in dollars
	 private double restockFee;         //price for restocking units


    //Constructors

    //Default constructor
    public Product4()
    {
        //Set some default values for each private variable
        name                  = "";
        identificationNumber  = 0;
		  unitsInStock          = 0;
        unitPriceInDollars    = 0.00;
		  restockFee            = 0.00;

    }//End Inventory constructor

    Product4 inventory [] = new Product4 [5];

    //Initialization constructor
    public Product4(
                    String nameIn, int identificationNumberIn, 
						  int unitsInStockIn, double unitPriceInDollarsIn, double restockFeeIn
                  )
    {

        //Set the item name--use the set methods to enforce bounds checking

I appreciate whatever assistance is offered. Thank you.
