Hi everyone!

Im new to the forum and this is my first post. I want to create a maze where i am able to move around with a dot. But i cant even create the maze it only shows a blank window and im rly confused in what to do.
So i hope u can help me, correct the code for me and tell me what do to next.

I would rly appreciate the help and ty in advance.

My code this far is:

Code java:

class Mazegame {
 
    public static void main(String[] args) {
	new Mazegame().run();
    }
 
    void run() {
	Game game = new Game();
	game.run();
    }
}
 
class Game {
 
    private DotWindow w;
    private int width;
    private int height;
 
    public void run() {
	setup();
    }
 
    private void setup() {
	w = new DotWindow(50, 50, 10);
	w.setDot(0, 25, Color.RED);
	generate(width, height);
    }
 
    private void generate(int width, int height) {
	width = Keyboard.nextInt("ange bredd: ");
	height = Keyboard.nextInt("ange höjd: ");
	int[][] maze = MazeGenerator.generate(width, height);
	for(int x = 1; x < width - 1; x++) {
	    for(int y = 1; y < height - 1; y++) {
 
	    }	
	}
    }
}
