arguments don't match datatype of constructor

[Freckles]

Thanks for the tips. I still haven't been able to get the 2-decimal point to work. But I've moved on to bigger and better and things for the moment.... I just have to make my items show up in a frame one at a time, which I've managed to figure out. But I want the entire application to close when I finish going through each window. I'm trying to use EXIT_ON_CLOSE, but it's not working properly. Can anyone tell me what I'm missing? This assignment is due tonight so any quick help would be GREATLY appreciated!!

public class InventoryGui extends JFrame //begin class InventoryGui
{
	public static void main( String args[])
	{
		Product[] item = new Product [4];

		Product item1 = new Plastic (1003182, "Polytrope TPP", 7, 1.81, "Black" );
		Product item2 = new Plastic (1003296, "Polyvin PVC", 3, 1.72, "Light Neutral" );
		Product item3 = new Plastic (1013972, "Polyvin PVC-DC", 5, 1.15, "Beige" );
		Product item4 = new Plastic (1019392, "Invision", 9, 1.57, "Medium Dark Pewter" );

		item[0] = item1;
		item[1] = item2;
		item[2] = item3;
		item[3] = item4;

		double all = 0.00;

		for (int total= 0; total < 4;total++)
		{
			all = all + item[total].value();
		}

		for (Product myProduct: item)
		{
			System.out.println(myProduct);
			System.out.println();
		}

		System.out.println("The Value of all items combined is: $"+all);

		JOptionPane.showMessageDialog( null, "The first item is: "+item1, "ASI Product Inventory", JOptionPane.PLAIN_MESSAGE ); //display first item
		JOptionPane.showMessageDialog( null, "The second item is: "+item2, "ASI Product Inventory", JOptionPane.PLAIN_MESSAGE ); //display second item
		JOptionPane.showMessageDialog( null, "The third item is: "+item3, "ASI Product Inventory", JOptionPane.PLAIN_MESSAGE ); //display third item
		JOptionPane.showMessageDialog( null, "The fourth item is: "+item4, "ASI Product Inventory", JOptionPane.PLAIN_MESSAGE ); //display fourth item
		JOptionPane.showMessageDialog( null, "The value of the entire inventory is: "+all, "ASI Product Inventory", JOptionPane.PLAIN_MESSAGE ); //display inventory value total

		InventoryGui inventoryGui = new InventoryGui(); //create InventoryGui
		inventoryGui.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); //set frame to close on exit

	} //end main method

} //end class InventoryGui

I think you better read up on swings...
couple of things you have some of your codes in the wrong order, and you are not using them correctly.
you also need to add(item),
setVisible(true )
Public static void main (String[] argements){
InventoryGui inventoryGui = new InventoryGui();
}

Here's what I added but I can still see it's wrong. Do I need to call each item[ ] ... and how do I do that if so?

 
public class InventoryGui extends JFrame //begin class InventoryGui
{
private JLabel items; // JLabel with just text 
public InventoryGui()
{
setLayout( new FlowLayout() );
items = new JLabel("text");
add(items);
}
public static void main( String args[])
{
InventoryGui inventoryGui = new InventoryGui(); //create InventoryGui
inventoryGui.setVisible( true ); // display frame
inventoryGui.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); //set frame to close on exit
Product[] item = new Product [4];
Product item1 = new Plastic (1003182, "Polytrope TPP", 7, 1.81, "Black" );
Product item2 = new Plastic (1003296, "Polyvin PVC", 3, 1.72, "Light Neutral" );
Product item3 = new Plastic (1013972, "Polyvin PVC-DC", 5, 1.15, "Beige" );
Product item4 = new Plastic (1019392, "Invision", 9, 1.57, "Medium Dark Pewter" );
item[0] = item1;
item[1] = item2;
item[2] = item3;
item[3] = item4;
double all = 0.00;
for (int total= 0; total < 4;total++)
{
all = all + item[total].value();
}
for (Product myProduct: item)
{
System.out.println(myProduct);
System.out.println();
}
System.out.println("The Value of all items combined is: $"+all);
JOptionPane.showMessageDialog( null, "The first item is: "+item1, "ASI Product Inventory", JOptionPane.PLAIN_MESSAGE ); //display first item
JOptionPane.showMessageDialog( null, "The second item is: "+item2, "ASI Product Inventory", JOptionPane.PLAIN_MESSAGE ); //display second item
JOptionPane.showMessageDialog( null, "The third item is: "+item3, "ASI Product Inventory", JOptionPane.PLAIN_MESSAGE ); //display third item
JOptionPane.showMessageDialog( null, "The fourth item is: "+item4, "ASI Product Inventory", JOptionPane.PLAIN_MESSAGE ); //display fourth item
JOptionPane.showMessageDialog( null, "The value of the entire inventory is: "+all, "ASI Product Inventory", JOptionPane.PLAIN_MESSAGE ); //display inventory value total
} //end main method
} //end class InventoryGui
