How do I make the movement of an Graphics2D Oval smooth

Question

Basically when i update the ball in my flipper (an Oval created with Graphics2D) it teleports to his next location, which is what I want it to do, but I would much rather have a smooth animation (And I also fear the crispy movement is gonna be hard to deal with for collisions).

So is there a way to get smoother movement?

The main class:

import Flipper.Ball;
import Flipper.Cabinet;

public class Main {

    public static Cabinet cabinet;
    public static Ball ball;

    public static void main(String[] args) throws InterruptedException {
        new Frame();
        cabinet = new Cabinet();
        ball = new Ball();

        while (true)
            update();
    }

    private static void update() throws InterruptedException {
        ball.calcSpeed();
        ball.move();
    }
}

Frame class:

import javax.swing.*;

public class Frame extends JFrame {

    Frame() {
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.add(new Panel());
        this.pack();
        this.setLocationRelativeTo(null);
        this.setVisible(true);
    }
}

Panel class (I left out all of the useless KeyListener/MouseListener methods that i haven't used yet):

mport javax.swing.*;
import java.awt.*;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

public class Panel extends JPanel implements KeyListener, MouseListener {

    Panel() {
        this.setPreferredSize(new Dimension(Constant.WIDTH, Constant.HEIGHT));
        this.setFocusable(true);
        this.addMouseListener(this);
        this.addKeyListener(this);
    }

    @Override
    public void paint(Graphics g) {
        super.paint(g);
        Graphics2D g2 = (Graphics2D) g;

        g2.setColor(Color.BLACK);
        g2.draw(Main.cabinet.getShape());

        g2.setColor(Color.BLUE);
        g2.fillOval(Main.ball.getX(), Main.ball.getY(), Constant.BALLSIZE, Constant.BALLSIZE);

        repaint();
    }
}

Flipper classes:

package Flipper;

import main.Constant;

import java.awt.*;

public class Cabinet {

    private Rectangle shape;
    public Cabinet() {
        this.shape = new Rectangle(Constant.WIDTH, Constant.HEIGHT);
    }

    public Rectangle getShape() {
        return shape;
    }
}

package Flipper;

import main.Constant;

import java.util.concurrent.TimeUnit;

public class Ball {

    private int x;
    private int y;
    private int xSpeed = 1;
    private int ySpeed = 10;

    public Ball() {
        this.x = 230;
        this.y = 160;
    }

    public void calcSpeed() {
        if (y >= Constant.HEIGHT - Constant.BALLSIZE)
            ySpeed = ySpeed * -1;
        if (y <= 0)
            ySpeed = ySpeed * -1;
    }

    public void move() throws InterruptedException {
        y += ySpeed;

        TimeUnit.MILLISECONDS.sleep(50);
    }

    // Getters


    public int getX() {
        return x;
    }

    public int getY() {
        return y;
    }

    public int getxSpeed() {
        return xSpeed;
    }

    public int getySpeed() {
        return ySpeed;
    }


    // Setters

    public void setX(int x) {
        this.x = x;
    }

    public void setY(int y) {
        this.y = y;
    }

    public void setxSpeed(int xSpeed) {
        this.xSpeed = xSpeed;
    }

    public void setySpeed(int ySpeed) {
        this.ySpeed = ySpeed;
    }
}
