我是一名大二学生，最近在学习Java中GUI相关内容时，用到了addMouseListener函数，但在建立new MouseListener时却报错了，但代码和书上一样，并且在室友电脑上也可以正常运行，请求各位前辈帮忙看一看，
具体代码如下：

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class MouseEvent {
    private static void createAndShowGUI() {
        JFrame f = new JFrame("MouseEvent");
        f.setLayout(new FlowLayout());
        f.setSize(300,200);
        f.setLocation(300,200);
        f.setVisible(true);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JButton but = new JButton("Button");
        f.add(but);

        but.addMouseListener(new MouseListener() {
            public void mouseReleased(MouseEvent e) {
                System.out.println("mouseReleased-鼠标放开事件");
            }
            public void mousePressed(MouseEvent e) {
                System.out.println("mousePressed-鼠标按下事件");
            }
            public void mouseExited(MouseEvent e) {
                System.out.println("mouseExited-鼠标移出按钮区事件");
            }
            public void mouseEntered(MouseEvent e) {
                System.out.println("mouseEntered-鼠标进入按钮区事件");
            }
            public void mouseClicked(MouseEvent e) {
                System.out.println("mouseClicked-鼠标完成单击事件");
            }
        });
    }
    public static void main(String[] args) {
        SwingUtilities.invokeLater(MouseEvent::createAndShowGUI);
}
}
