If anybody knows the command/method used to alter the transparency of a fillRect() for paint that would be great. I tried looking it up and saw that it might be called alpha to alter this, however I can't figure out how to change alpha. The only command i can see is getAlpha(). If anyone could provide me with an example that would be great. I'm sure I can figure it out from there!

Thanks in advance!

Use a transparent color.

Color has multiple constructors. The one that takes 4 int arguments is the one you want. The last argument is the "alpha":

Color color = new Color(255, 0, 0, 100);

void onPaint(Graphics2D g) {
    g.setColor(color);
    g.fillRect(...);
}

It is worth noting that, like the RGB values, the alpha constructor is also in the range 0-255 where 255 is solid colour.
