Serialization compiler error

Ok this is an inner class in my BeatBox class.

public class MyLoadListener implements ActionListener {
public void actionPerformed(ActionEvent a) {

JFileChooser fileOpen = new JFileChooser();
File myFile = fileOpen.getSelectedFile();

try {

FileInputStream fileReader = new FileInputStream(myFile);
ObjectInputStream os = new ObjectInputStream(fileReader);
checkboxState = (boolean[]) is.readObject();

} catch(Exception ex) {



for (int i = 0; i < 256; i++) {
JCheckBox check = (JCheckBox) checkBoxList.get(i);
if(checkboxState[i]) {
} else {

} // end of for loop


} // end of method

} // end of inner class

Now when I try to compile this, I get this error message complaining about my is variable, see below. Now I know I must just be missing something stupid so, if anyone can help that'd be great. cannot find symbol
symbol : variable is
location: class BeatBox.MyLoadListener
checkboxState = (boolean[]) is. readObject();

the ^ is supposed to be under is, but I can't seem to get it to stick there

Teaching yourself anything is always the cheapest way, but it definitely takes a lot of time and effort.<br /> <br />Thank you javaranch <a href="http://""" target="_blank" rel="nofollow">Learn How to Ask Your Question</a> and be nice

It doesn't look like you've declared the variable "is".

This is why god invented other people. Just so they can look at something so painfully obvious that it hurts. Thank you very much, I've staring at that for roughly 2 hours.

and the compiler message

cannot find symbol
symbol : variable is

didn't give you a clue? Basically, that's exactly what Kristin said.
I agree. Here's the link:
