Thread: wrong graphics

private void drawNode(double x, double y, double no, Graphics g) {
		g.fillOval(x, y, 17, 17); // draw an oval which is filled with the current color
		g.setColor(blue); // set current color to black
		g.drawOval(x, y, 16, 16); // draw an oval
		g.drawString(Integer.toString(no), x+5, y+13); // draw the node number
}

The code above is wrong in netbeans, it said the fillOval(), drawOval, drawString() cannot have the a double value, so how can i solve it? Please help!!
Thank you

Read the API for Graphics. Those methods take int parameters. Evidently you are passing doubles instead of ints, so why are you doing that?

Because my x and y is a double value, is it i can passed a double value into it? i want to be more accurate, so i want it to be a double value for x and y.

The values passed to these methods relate to pixels, and pixels do not have fractions. You can fix the problem by casting the doubles to int's.

i want to be more accurate

Then you'll need to cast the Graphics to Graphics2D and use the methods of the Graphics2D class, along with anti-aliasing.

Be aware that it could be a steep learning curve for someone at your level (no offence, we all have to start somewhere, but by that I mean someone who attempts to pass double values where the API clearly shows int parameters).

What's so inaccurate about rounding pixel values to integers anyhow?
