JButton not sending action command

I am working on a school project and I'm having a dickens of a time trying to get the JButton to do..well.. anything! this is my code, I don't know how important the other .java files are.

I started with a simple code that worked but after adding and editing it can't seem to update the text exactly how I want it.

    <removed>

var1, var2, etc. that are being passed in are stored as such..

they are all in another .java file

the Function.fun

Okay...

  1. Don't rely on static, it's not going to help you and will create a whole lot of new issues which will be difficult to solve
  2. The main problem is, your code is generating a NumberFormatException - java.lang.NumberFormatException: For input string: "javax.swing.JSpinner[,8,6,109x26,invalid,layout=com.apple.laf.AquaSpinnerUI$SpinnerLayout,alignmentX=0.0,alignmentY=0.0,border=,flags=16777536,maximumSize=,minimumSize=,preferredSize=]"

So, based on the exception, it's obvious that Double.parseDouble isn't getting the value it excpects

So, having a deeper look at your code...

if (jspValue1.getValue() instanceof Double) {
    s = jspValue1.toString();
    d = Double.parseDouble(s);
    return d;
} else {
    return 0.00;
}

You're passing the result of jspValue.toString to Double.parseDouble, but he fact is, it's just not required.

You've already determined that the value from the JSpinner is a double, so you on;y need to cast it...

double value = 0.00d;
if (jspValue1.getValue() instanceof Double) {
    value = (Double)jspValue1.getValue();
}
return value;
