如何在使用鼠标单击并拖动Jframe时使其移动

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

public class DraggableFrame extends JFrame {
    private int mouseX, mouseY;

    public DraggableFrame() {
        setTitle("Draggable JFrame");
        setSize(400, 300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null); // Center the frame on the screen

        // Add a MouseAdapter to handle dragging
        addMouseListener(new MouseAdapter() {
            @Override
            public void mousePressed(MouseEvent e) {
                mouseX = e.getX();
                mouseY = e.getY();
            }
        });

        addMouseMotionListener(new MouseAdapter() {
            @Override
            public void mouseDragged(MouseEvent e) {
                int newX = getX() + e.getX() - mouseX;
                int newY = getY() + e.getY() - mouseY;
                setLocation(newX, newY);
            }
        });
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            DraggableFrame frame = new DraggableFrame();
            frame.setVisible(true);
        });
    }
}
