如何缓慢地（像效果一样）移动标签（图像）以摆动鼠标在JAVA中的位置

Question

I want to make a GUI program that, when I press mouse button, moves label to the position of pressed X and Y locations. I did that, it was easy, but I want to make it now like a slow moving effect. I tried to do it with thread.sleep() but it didn't work. Can you help me with ideas or code? This is my code:

import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;

public class jGame extends JFrame {

private JPanel contentPane;

public static void main(String[] args) {
    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                jGame frame = new jGame();
                frame.setVisible(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}

public jGame() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 568, 459);
    contentPane = new JPanel();
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    setContentPane(contentPane);
    contentPane.setLayout(new BorderLayout(0, 0));

    JPanel panel = new JPanel();
    contentPane.add(panel, BorderLayout.CENTER);

    JLabel robot = new JLabel("");
    robot.setIcon(new ImageIcon("/home/ubuntu/Desktop/robot.png"));
    panel.add(robot);
    panel.addMouseListener(new MouseListener() {

        @Override
        public void mouseClicked(MouseEvent e) {
            robot.setLocation(e.getX() - 25, e.getY() - 40);
        }

        @Override
        public void mouseReleased(MouseEvent e) {

        }

        @Override
        public void mousePressed(MouseEvent e) {

        }

        @Override
        public void mouseExited(MouseEvent e) {

        }

        @Override
        public void mouseEntered(MouseEvent e) {

        }
    });
}

}

And here is the image I use:

Answer 1

Writing is half the fun...

1. Store the startPoint & nextStep as Points
2. Initialize a javax.swing.Timer
3. When user clicks, save the Root startPoint , set nextStep to mouse location and call timer.start() .
4. Timer.actionPerformed() needs to calculate the nextStep Point as it moves back to startPoint .
5. if startPoint equals nextStep call timer.stop()
