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
CODE


    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:

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


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

java
numberOfBoxesJSpinner.getValue();

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

I was thinking
CODE

        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...
CODE

        //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:

java

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
CODE

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

        contentPane.add(numberOfBoxesJSpinner);


and my calculatesubTotal
CODE

    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

java

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

    }

This compiles

java

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 smile.gif

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.
