g.fillRect(110,110,80,80);
// change colors again
g.setColor(weirdColor);
// a circle (int x, int y, int width, int
height,int startAngle, int arcAngle);
// ovals are also possible this way.
g.fillArc(120,120,60,60,0,360);
g.setColor(Color.yellow);
// Draw a line (int x1, int y1, int x2,
int y2)
g.drawLine(140,140,160,160);
// reset the color to the standard color
for the next time the applets paints
// an applet is repainted when a part
wasn't visible anymore
// happens most often because of browser
minimizing or scrolling.
g.setColor(Color.black);
}
}
// that's some basic drawing.
// next is drawing images on screen
// go to imageExample.java
