Closest x and y ??

[GNecro1]

how to seperate the closest x and y and go to that direction
my code

	int targetX = x;
	int targetY = y;
	public int speed = 5;
	public int dirY, dirX;

	public void moveLogic() {
		getFood1();
		if (targetX != x || targetY != y) {
			int pathX = targetX - x;
			int pathY = targetY - y;

			double distance = Math.sqrt(pathX * pathX + pathY * pathY);
			double directionX = pathX / distance;
			double directionY = pathY / distance;

			double movementX = directionX * speed;
			double movementY = directionY * speed;
			dirX = (int) movementX;
			dirY = (int) movementY;
		}
		move();
	}

	public void move() {
		x += dirX;
		y -= dirY;
	}

	public void getFood1() {
		if (targetX == x && targetY == y) {
			int[] foodX = new int[game.food.size()];
			int[] foodY = new int[game.food.size()];

			for (int i = 0; i < game.food.size(); i++) {
				foodX[i] = game.food.get(i).x;
				foodY[i] = game.food.get(i).y;
			}
			for (int i = 0; i < foodX.length; i++) {
				for (int j = 0; j < foodY.length; j++) {
					if (game.food.get(i).x - x < 40) {
						targetX = game.food.get(i).x;
						if (game.food.get(i).y - y < 40) {
							targetY = game.food.get(i).y;
						}
					}
				}
			}
		}
	}

and it is not working please help
