I need Help with my Game

Hey guys i'm encountering a problem with my code. I am following a youtube tutorial and i have all the correct code, in which is supposed to display lots of pixels when ran.

My code is the exact same but when i run, all i get is a blank screen

Please help and this is my Code;

import java.awt.Canvas;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.image.BufferStrategy;
import java.awt.image.BufferedImage;
import java.awt.image.DataBufferInt;
import java.util.Random;

import javax.swing.JFrame;


public class Game extends Canvas implements Runnable {


private static final long serialVersionUID = 1L;
public static final int HEIGHT = 120;
public static final int WIDTH = 120;
public static final int SCALE = 3;

public static final String NAME = "My First Game!";

private BufferedImage image = new BufferedImage(WIDTH, HEIGHT, BufferedImage.TYPE_INT_RGB);
private int[] pixels = ((DataBufferInt) image.getRaster().getDataBuffer()).getData();

Random random = new Random();

private boolean running = false;

public void start() {
running = true;
new Thread(this).start();

}

public void run() {
while (running) {
tick();
render();
}
}
public void stop(){

running = false;
}

public void tick() {
for(int i = 0; i < pixels.length; i++) {
pixels = random.nextInt();
}
}
public void render(){
BufferStrategy bs = getBufferStrategy();
if(bs == null) {
createBufferStrategy(3);
requestFocus();
return;
}

Graphics g = bs.getDrawGraphics();
g.drawImage(image, 0 , 0, getWidth(), getHeight(), null);
g.dispose();
bs.show();



}

public static void main(String[] args) {

Game game = new Game();
game.setPreferredSize(new Dimension(WIDTH * SCALE, HEIGHT * SCALE));
game.setMaximumSize(new Dimension(WIDTH * SCALE, HEIGHT * SCALE));
game.setMinimumSize(new Dimension(WIDTH * SCALE, HEIGHT * SCALE));

JFrame frame = new JFrame(NAME);
frame.add(game);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setResizable(true);
frame.setVisible(true);

}

}


Thank's in advance
