Анимированная строка в рамке

Question

Я пытаюсь изучить анимацию на Java и хочу создать рамку, которая отображает строку и анимирует эту строку так, чтобы она перемещалась по экрану, управляемому клавишами со стрелками, и обеспечивала его нахождение за границами экрана.

Я уже сделал то же самое с мышью, но я не могу сделать это с помощью клавиш со стрелками

package Draw;

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

public class DrawMouse extends JPanel implements MouseListener, MouseMotionListener, KeyListener
{
    int x, y;
    String s = "Drag this around";

    boolean click, drag, mouseInside, insideR1, insideR2, insideR3;

    //create 3 rectangle objects
    Rectangle r1 = new Rectangle (20, 70, 80, 100);
    Rectangle r2 = new Rectangle (110, 70, 80, 100);
    Rectangle r3 = new Rectangle (200, 70, 80, 100);

    // create the fonts once and use them when needed
    Font bigFont = new Font ("Helvetica", Font.BOLD, 45);
    Font size12 = new Font ("Helvetica", Font.BOLD, 12);
    Font size14 = new Font ("Helvetica", Font.PLAIN, 14);

    public DrawMouse ()
    { // add the listener to the panel
        addMouseListener (this);
        addMouseMotionListener (this);
        this.addKeyListener (this);
        setFocusable (true); // need this to set the focus of the mouse
    }

    //generates only one event for each pressed-released combination

        //"contains" is a method of the Rectangle class
        if (r1.contains (x, y))
            insideR1 = true;
        else
            insideR1 = false;

            s = "";

    public void drawStuff (Graphics g)
    {
        //if mouse was clicked,      background magenta, otherwise black
        if (click)
        {

        if (drag)
            g.drawString (s, x, y);
        else
            g.drawString (s, 20, 200);

        //draw the mouse coordinates
        if (mouseInside)

            g.drawString ("X:  " + x, 30, 30);
            g.drawString ("Y:  " + y, 30, 50);
        }
        else
        {
            g.setFont (size14);

        }

        if (insideR1)
        {
            g.setFont (bigFont);
            g.setColor (Color.blue);
            g.drawString ("BLUE", 120, 50);
            g.setColor (Color.white);
            g.drawRect (r1.x, r1.y, r1.width - 1, r1.height - 1);
        }

        if (insideR2)
        {
            g.setFont (bigFont);
            g.setColor (Color.green);
            g.drawString ("GREEN", 120, 50);
            g.setColor (Color.white);
            g.drawRect (r2.x, r2.y, r2.width - 1, r2.height - 1);
        }

        if (insideR3)
        {
            g.setFont (bigFont);
            g.setColor (Color.red);
            g.drawString ("RED", 120, 50);
            g.setColor (Color.white);
            g.drawRect (r3.x, r3.y, r3.width - 1, r3.height - 1);
        }
    }

    public void paintComponent (Graphics g)
    {
        super.paintComponent (g);
        drawStuff (g);
    }

    public static void main (String[] args)
    {
        JFrame frame = new JFrame ("DrawMouse");
        frame.getContentPane ().add (new DrawMouse ());
        frame.setSize (300, 300);
        frame.setVisible (true);
        frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
    }
}

Я ожидаю получить тот же вывод, но переместить строку с помощью клавиш со стрелками не с мышью
