set pixel in frame

[Tian Zhang]

hi there!

i have a class that extends JFrame, i was wondering if it is possible to set (draw) individual pixels within the frame, i.e. something that looks like:

setColor(int x, int y, Color c)

at the moment i'm considering (which is probably inefficient):

Graphics g = myClass.getGraphics();
g.drawLine(x, y, x, y);

thanks,
tian.
