• The coordinates in Java start as o,o in upper left hand corner
• to draw a line just name the 2 points in drawLine
• to draw a square or rectangle name name the upper left hand corner points (x,y) then how wide and then how tall
• to draw an oval or circle - name upper left hand corner of the box it would be in and then name the width and height (they will be equal for circle)

//draw house
g.setColor(Color.green);
g.drawLine(0, 350, 400, 350);

g.setColor(Color.red);
g.drawRect(100, 200, 150, 150);
g.setColor(Color.black);
g.fillRect(150, 275, 50, 75);
g.drawPolygon(xPoints, yPoints, 3);
g.setColor(Color.yellow);
g.fillOval(300, 75, 50, 50);
Advanced
To use the drawPolygon command we must first create 2 integer arrays with the x and y coordinates of the points we want to connect. In the example below we are connecting points 75,200 to 175,250 to 275,200. The third argument in the drawpolygon command is the size of the arrays.

int xPoints[] = {75, 175, 275};
int yPoints[] = {200, 250, 200};
