In Java, I've been trying to cast a JSpinner number input to an integer using Netbeans. I've made it so that the JSpinner input is a number, but I can't try to cast it to my own integer without receiving errors. I've tried many various things and one of the errors I most commonly receive is "Inconvertible types, required int, found JSpinner." How would I just simply be able to assign a JSpinner input (preferably a number) to an integer.

    *"I've tried many various things"* For better help sooner, post an [SSCCE](http://sscce.org/) of the one you think is closest to working. – Andrew Thompson May 04 '13 at 04:11

You can't cast the spinner itself to a number. You need to get its value. You can use:

((SpinnerNumberModel) spinner.getModel())).getNumber().intValue()

This will only work if the underlying model is a SpinnerNumberModel (default). You could also use:

Object o = spinner.getValue();
Number n = (Number) o;
int i = n.intValue();

This will work as long as the value can be cast to a Number.

  • @Mel yes, true; this is example code, not production code. In reality I'd keep a reference to the original model. – wchargin May 04 '13 at 04:15
