java - 让 Swing Timer 执行 N 次？

Question

我该如何调整这个 Timer代码使其执行四次然后停止？

timer = new Timer(1250, new java.awt.event.ActionListener() {
    @Override
    public void actionPerformed(java.awt.event.ActionEvent e) {
         System.out.println("Say hello");
    }
});
timer.start();

你可以这样做:

Timer timercasovac = new Timer(1250, new ActionListener() {
    private int counter;

    @Override
    public void actionPerformed(ActionEvent e) {
        System.out.println("Say hello");
        counter++;
        if (counter == 4) {
            ((Timer)e.getSource()).stop();
        }
    }
});
timercasovac.start();
