Find the error(s) in the following code, which should handle the event that occurs when the value in itemsJSpinner changes.

Question

```
1 itemsJSpinner.addChangeListener(
2
3 new ChangeListener() // anonymous inner class
4 {
5 // event handler called when value in itemsJSpinner is changed
6 public void valueChanged( ChangeEvent event )
7 {
8 itemsJSpinnerValueChanged( event );
9 }
10
11 } // end anonymous inner class
12
13 ); // end call to addChangeListener
```

Answer 1

The event handler must be named stateChanged. Note: The programmer-declared method should also be changed to be named itemsJSpinnerStateChanged to follow our naming guidelines.

```
1 itemsJSpinner.addChangeListener(
2
3 new ChangeListener() // anonymous inner class
4 {
5 // event handler called when value in itemsJSpinner is changed
6 public void stateChanged( ChangeEvent event )
7 {
8 itemsJSpinnerStateChanged( event );
9 }
10
11 } // end anonymous inner class
12
13 ); // end call to addChangeListener
```
