Why doesn't anonymous class work in java?

Question

Java

//add action listener for alpha
alpha.addActionListener(new ActionListener() {
public void actionPerfomend(ActionEvent ae){
lab.setText("Alpha button pressed");
}
});

Answer 1

What exactly doesn't work? Have you looked in the debugger? Deliver banal System.out.println
Give more information.

//добавляем слушатель действий для альфа
alpha.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent ae){
        System.out.println("В аннонимом классе");
        lab.setText("Нажата кнопка Альфа");
    }
});

you also have a typo instead of actionPerfomend should beactionPerformed
