OK here is my program so far and I'm getting a compile error on my constructor located in class Inventory on line 50

here is my subclass of DVD

public class DVD
{

	//declare variables
	String DvdTitle = "";
	double ItemNumber = 0.00;
	double DvdPrice = 0.00;
	int NumberInStock = 0;

		this.ItemNumber = ItemNumber;
		this.DvdPrice = DvdPrice;
		this.NumberInStock = NumberInStock;
		this.restockFee = RestockFee;
	}

	//get and set methods
	public String getDvdTitle()
	{
		return DvdTitle;
	}

	public void setDvdTitle(String DvdTitle)
	{
		this.DvdTitle = DvdTitle;
	}

	public double getItemNumber()
	{
		return ItemNumber;
	}

	public void setItemNumber(double ItemNumber)
	{
		this.ItemNumber = ItemNumber;
	}

	public double getDvdPrice()
	{
		return DvdPrice;
	}

	public void setDvdPrice(double DvdPrice)
	{
		this.DvdPrice = DvdPrice;
	}

	public int getNumberInStock()
	{
		return NumberInStock;
	}

	public void setNumberInStock(int NumberInStock){
		this.NumberInStock = NumberInStock;
	}

	public double getRestockFee(){
		return (NumberInStock * DvdPrice * .05);
	}
}// End Class DVD

Because you have constructor for 5 parameters public DVD (String DvdTitle, double ItemNumber, double DvdPrice, int NumberInStock, double RestockFee) but passing only 3 new DVD(DvdTitle, ItemNumber, DvdPrice, NumberInStock); . Create another constructor that will accept only 3 parameters and you done

Thanks,
I made the constructor to pass all 5 parameters all of my code is the same until this section, which now gives me an error that states:
variable DvdTitle might not have been initialized
it references what in this post is line # 14

DVD newDVD = new DVD(DvdTitle, ItemNumber, DvdPrice, NumberInStock, RestockFee);
			   
			//Put the dvd you just created into the array of DVDs.

			myDVD[count] = newDVD;
		}//end for
		
		double DvdValue = (DvdPrice*NumberInStock);
		
		//double totalInventory = computeValue();
		for (int i = 0; i<count; i++)
		{//print information from array
			System.out.println("DVD Title:" + DvdTitle);
			System.out.println("Item Number:" + ItemNumber);
			System.out.println("Price:" + DvdPrice);
			System.out.println("Number in Stock:" + NumberInStock);
			System.out.println("Stock Value:" + DvdValue);
			System.out.println();//blank line
		}//end for

variable DvdTitle might not have been initialized

Where is the variable: DvdTitle initialized?
The compiler wants you to assign it a value before you try to use it.
