遇到ActionListener java问题

Question

Getting an Error when i try to add a second Action Listener. I have two different JButtons set up and have one of them working ok but when i try add a Action Listener for the second one i get the following error:

is not abstract and does not override abstract method actionPerformed(ActionEvent) in     ActionListener
    next.addActionListener(new ActionListener (){

and this is the code of the two Action Listeners.

    next.addActionListener(new ActionListener (){
        public void preformedAction(ActionEvent e){

        }
    });

    close.addActionListener(new ActionListener (){
        public void actionPerformed(ActionEvent event){
            frame.dispose();        //Closes Window
        }//End ActionPreformed
    });//End Of Close Action

the two buttons are "next" and "close"

Answer 1

The method you need to override is actionPerformed(ActionEvent) , not preformedAciton(ActionEvent) . The ActionListener you are creating and adding to next uses the latter method signature, which is incorrect, and thus the error.
