I'm trying to create a 10x10 grid using for loops in Java. I'm able to create rows going up and down but not repeating.

            for(int i = 1; i < temperatures.length; i++) {
                temperatures[i] = (temperatures[i-1] + 12) / 2; //takes average of 12 and previous temp
            }
        }

        public void paint(Graphics g) {
            for(int y = 1; y < 9; y++) {
                g.setColor(Color.black);
                g.drawRect(10, 10, 10, 10);
                g.drawRect(10, 10, 10, 20);
                g.drawRect(10, 10, 10, 30);
                g.drawRect(10, 10, 10, 40);
                g.drawRect(10, 10, 10, 50);
                g.drawRect(10, 10, 10, 60);
                g.drawRect(10, 10, 10, 70);
                g.drawRect(10, 10, 10, 80);
                g.drawRect(10, 10, 10, 90);
                g.drawRect(10, 10, 10, 100);

                for(int x = 1; x < 9; x++) {
                g.setColor(Color.black);
                g.drawRect(10, 10, 10, 10);
                g.drawRect(10, 10, 20, 10);
                g.drawRect(10, 10, 30, 10);
                g.drawRect(10, 10, 40, 10);
                g.drawRect(10, 10, 50, 10);
                g.drawRect(10, 10, 60, 10);
                g.drawRect(10, 10, 70, 10);
                g.drawRect(10, 10, 80, 10);
                g.drawRect(10, 10, 90, 10);
                g.drawRect(10, 10, 100, 10);
            }
        } 
    }
}
