Help with added constructor in subclass in array
I am writing a program that needs to have a subclass that adds a new constructor and adds in a 5% restocking fee. I have everything working except the new constructor. My new constructor should add the manufacturer name. My question is, now when I sort my array alphabetically by product name (folders, glue, markers, etc.) the newly added manufacturer name (Bic, Mead, Stanley, etc.) does not coincide with the right product. How do I get the newly added constructor in my subclass to stay with the right product?
Here is my first set of output with correct information:
Product name : pens
Manufacturer : Bic
Item number : 1
Piece's in stock : 346.0
Unit price : $1.59
Product name : pencils
Manufacturer : Mead
Item number : 2
Piece's in stock : 487.0
Unit price : $0.59
Product name : markers
Manufacturer : Sharpie
Item number : 3
Piece's in stock : 168.0
Unit price : $1.29
Product name : paperclips
Manufacturer : Dennison
Item number : 4
Piece's in stock : 136.0
Unit price : $1.19
Product name : glue
Manufacturer : Elmer's
Item number : 5
Piece's in stock : 72.0
Unit price : $0.79
Product name : tape
Manufacturer : 3m
Item number : 6
Piece's in stock : 127.0
Unit price : $0.49
Product name : paper
Manufacturer : Mead
Item number : 7
Piece's in stock : 203.0
Unit price : $1.79
Product name : staples
Manufacturer : Pentech
Item number : 8
Piece's in stock : 164.0
Unit price : $1.19
Product name : folders
Manufacturer : Mead
Item number : 9
Piece's in stock : 238.0
Unit price : $0.49
Product name : rulers
Manufacturer : Stanley
Item number : 10
Piece's in stock : 123.0
Unit price : $0.17

Unit price : $1.59
The value of pens left in the inventory, plus a 5% restocking fee is: $577.65
Product name : rulers
Manufacturer : Pentech
Item number : 10
Unit price : $0.17
The value of rulers left in the inventory, plus a 5% restocking fee is: $21.96
Product name : staples
Manufacturer : Mead
Item number : 8
Unit price : $1.19
The value of staples left in the inventory, plus a 5% restocking fee is: $204.92
Product name : tape
Manufacturer : Stanley

Here is my subclass Maker.java where the new constructor manufact has been added.
package inventorymain;
publicclass Makerextends Inventory
{
protected String manufact;
public Maker(long itemNum, String name,double price,long units, String manufact)// Constructor for varibles
{
super(itemNum, name, price, units);
this.manufact = manufact;
}
publicvoid setManufact(String manufact)
{
this.manufact = manufact;
}
public String getManufact()
{
return manufact;
}
publicdouble getSum()//method to calculate sum
{
double itemTotal;
double stockFee;
itemTotal = (productUnits * unitPrice);
stockFee = itemTotal + (itemTotal * .05);
return stockFee;
}
}// end of class Maker

Hopefully someone can give me some direction. Thank you in advance!
