JSlider问题:在leftclick之后的位置

import javax.swing.*;

public class JSliderDemo {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            JSlider slider = new JSlider(0, 100, 50);
            slider.addChangeListener(e -> {
                System.out.println("Current value: " + slider.getValue());
            });
            JFrame frame = new JFrame("JSlider Demo");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.getContentPane().add(slider);
            frame.pack();
            frame.setVisible(true);
        });
    }
}
