Can't get this to compile, what am I doing wrong?

OK so I can see the "setUniqueType" on line 33 and the "ItemDetails" on line 50 are what need to be corrected, but I can't figure out what's wrong with it and how to fix it. Please help so I can move in with my program...

1. Your ItemDetails class has no setUniqueType method. You should add one.
2. The constructor you're using at :48 is "String, double, double, double, String" but your constructor is really only "String double double double" Either remove Type or add a String parameter to the end of your Item constructor, or make an ItemDEtails constructor with the five parameters.
3. Your ItemDetails has no constructor that matches that argument. If you want to chain the constructor, declare it in ItemDetails

Chaining the constructor:

public ItemDetails(String productName, double productNumber, double unitsInStock, double unitPrice
    super(productName,productNumber,unitsInStock,unitPrice);
}

Regarding ItemDetails: it looks like your ItemDetails constructor, inherited from Items, takes only 4 args and you're passing it 5.
