如何在java eclipse中将计时器文本显示在同一行中？

JLabel timerLabel = new JLabel("00:00:00");

Timer timer = new Timer(1000, new ActionListener() {
    int seconds = 0;
    int minutes = 0;
    int hours = 0;

    @Override
    public void actionPerformed(ActionEvent e) {
        seconds++;
        if (seconds == 60) {
            seconds = 0;
            minutes++;
            if (minutes == 60) {
                minutes = 0;
                hours++;
            }
        }
        String time = String.format("%02d:%02d:%02d", hours, minutes, seconds);
        timerLabel.setText(time);
    }
});

JFrame frame = new JFrame("Timer Example");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(timerLabel);
frame.pack();
frame.setVisible(true);
