public class GRectDemo {

static final int BAR_WIDTH = 40;


public static void main(String[] args) {

// Start by building the rectangle

GRect bar = new GRect(0,460, BAR_WIDTH, 8);
bar.setColor(Color.DARK_GRAY);
bar.setFilled(true);

// Then build a canvas to hold the rectangle

GCanvas gc = new GCanvas();
gc.setPreferredSize(new Dimension(BAR_WIDTH, 40));

gc.add(bar);
why does rectangle flip to top of screen?

Answer 1

Here in this code you wrote:
GRect bar = new GRect(0,460, BAR_WIDTH, 8);
bar.setColor(Color.DARK_GRAY);
bar.setFilled(true);

this parameter (0,460)- flips rectangle to top of screen.
