maybe I am a fool but, How?

I am not trying to not do this i am just lost, I guess...

getValue() in javax.swing.JSpinner cannot be applied to (javax.swing.JSpinner) I tried this


	public void enterJButtonActionPerformed(ActionEvent event)
		{
		itemIndex = brandJComboBox.getSelectedIndex();
		brandName = BrandArray[itemIndex];

		determineValue.setIndexOfValue(itemIndex);
		brandPrice = determineValue.getPricePerBox();

		calculatesubTotal();
	//	calculatesalesTax();
		displayOutput();
		}


	public void calculatesubTotal()
	{
		subTotal = numberOfBoxesJSpinner.getValue(numberOfBoxesJSpinner);
		determineValue.setIndexOfValue(itemIndex);
	}

No problem. You've initialised a JSpinner like this:

numberOfBoxesJSpinner = new JSpinner(new SpinnerNumberModel(0, 0, 5,1));

When you want the value of that one, just use the line:

numberOfBoxesJSpinner.getValue();

that was helpful, but, how do i multiply the numberOfBoxes by the price per box?

I was thinking

		subTotal = (numberOfBoxesJSpinner.getValue()) * brandPrice;

hmm, as i look at it, it doesn't make sense... and of course i get an error...

operator * cannot be applied to java.lang.Object,double

wait just referred to my notes i think i may have figured it out...

		//get Input
		firstNumber = Integer.parseInt(firstNumberJTextField.getText());
		secondNumber = Integer.parseInt(secondNumberJTextField.getText());	
		
		//add Numbers
		finalNumber = firstNumber + secondNumber;
		
		displayResults();

just got to adjust for my current scheme... right?

Or assign a temp double variable to spinner.getValue() then multiply it by brandPrice.

I haven't personally used a JSpinner but the following should work:

double temp = numberOfBoxesJSpinner.getValue();
 subTotal = temp * brandPrice;

edit: Your spinner is filled with doubles right? If it keeps returning just "Object" type cast it to a double.

ahh no?
spinner

		numberOfBoxesJSpinner = new JSpinner(new SpinnerNumberModel(0, 0, 5,1));
		numberOfBoxesJSpinner.setBounds(190,40, 50, 20);

		contentPane.add(numberOfBoxesJSpinner);

and my calculatesubTotal

	public void calculatesubTotal()
	{
	double temp = numberOfBoxesJSpinner.getValue();
   	subTotal = temp * brandPrice;

	}

i get an error code
incompatible types
am i doing something wrong?

Ok so based on your declaration it holds integers. edit: Or at least it holds 0-5 steps in 1 increments so integers

public void calculatesubTotal()
    {
    int temp = (int) numberOfBoxesJSpinner.getValue(); //type cast
       subTotal = temp * brandPrice;

    }

This compiles

public void calculatesubTotal()
{
        Object temp =  numberOfBoxesJSpinner.getValue();
        int num = Integer.parseInt(""+temp);
       subTotal = num * brandPrice;

}

edit: It works, just have to call displayOutput() after sub totaling

What are you trying to do ?

Yes it will and it does. getValue() returns an object. For whatever reason, java won't let me do an easy type cast. So I parsed the integer from the object and performed the calculations.

JSpinner.getValue(), Earlier in the thread, we tried C style casting, but apparently that is illegal if an Object is getting returned. It should return an Integer (at least I think that), but it doesn't. I think its an acceptable workaround for the time being.
