Action Event help

Sep 3rd, 2005

Hi, I've created a GUI program that has JButtons for like a menu. I am trying to get the action listener to do a whole other method.
EXample:

view.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{

menu();
System.exit(0);

}

But, It will not go to the method. It displays an error message that says: "unreported exception java.io.IOException; must be caught or declared to be thrown"
I am unsure if I must throw an IOException, or even how to throw and actionListener.
