How to add exception to actionPerformed?

Question

I have code that looks like this, with the main panel using an action listener in a different class in the same file:
public class MyPanel
    public MyPanel()
    //Panel code
    button.addActionListener(new MyButton());
private class MyButton implements ActionListener
    public void actionPerformed(ActionEvent e)
    //I want to throw a FileNotFoundException here, but when
    //I compile it, I get:
    //actionPerformed in Panel.java cannot implement actionPerformed in
    //java.awt.event.ActionListener; overridden method does not throw FileNotFoundException
        Scanner scan = new Scanner(new File("Items.txt"));
    }Any help would be appreciated. Thanks

Answer 1

I know how to catch an exception once it is thrown, I am having trouble declaring the method will throw an exception. When I put
public void actionPerformed(ActionEvent e) throws Exceptionand try to compile, it gives me a compiler error (the one in my first post.) I have tried declaring the exception in all other actionPerformed methods in my file, but have had no luck as they will all have a compiler error. I have no clue what to do to fix it.
