为什么要使用按键绑定而不是按键侦听器来提高用户输入的响应速度？

import java.awt.event.*; // Import event handling classes

public class KeyBindingExample {

    public static void main(String[] args) {
        // Create a JLabel component
        JLabel label = new JLabel();

        // Add key bindings to the JLabel
        label.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_UP), "moveUp");
        label.getActionMap().put("moveUp", new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // Perform action for "move up" key
            }
        });
    }
}
