Im on a windows and when i try to run it as a java application it gives an error

That mathematical operation is unnecessary:
 gameWidth = canvasWidth / factor * xDiff / factor;
 gameHeight = canvasHeight / factor * yDiff / factor;
To set the width and height of the frame to the width and height of the screen, respectively, use:
 gameWidth = screenSize.width;
 gameHeight = screenSize.height;

The while loop seems unnecessary, take the floored quotient of the screen dimensions and choose which ever is smaller as the aspect ratio, and make your gameWidth and height equal to the defaults. Great vids though!

int widthRatio = (int) / DEFAULT_GAME_WIDTH));
int heightRatio = (int) / DEFAULT_GAME_HEIGHT));

int factor = Math.min(widthRatio, heightRatio);

canvasWidth = factor * DEFAULT_GAME_WIDTH;
canvasHeight = factor * DEFAULT_GAME_HEIGHT;

I'm confused, why don't you just set the screen size to full screen?:



That's what I did, is it because you want everything scaled at a precise rate?
