custom cursor

I searched this board a few days ago when I was looking into how to create a custom cursor and found a few posts asking the same question but no answers so I thought i'd post a working solution. Used as a method of a class that extends BApplet it seems to work for me. (BTW, I just started learning java last week so this may very well not be the optimal way of doing it, but it might save someone some time.)
import java.awt.Cursor;
import java.awt.Dimension;
import java.awt.Toolkit;
import java.awt.Image;
import java.awt.Point;
private final void customizeCursor() {
Toolkit toolkit = getToolkit();
Dimension allowedDimensions = toolkit.getBestCursorSize(16, 16);
System.out.println("allowed dimensions = "+allowedDimensions.width);
int allowedColours = toolkit.getMaximumCursorColors();
if (!allowedDimensions.equals(new Dimension(0, 0)) && (allowedColours != 0)) {
Image pencil;
if(allowedDimensions.width>16) {
pencil = reference to a 32x32 pixel image that you've previously loaded;
}else {
pencil = reference to a 16x16 pixel image that you've previously loaded;
}
if (pencil != null) {
try {
Cursor pencilcursor = toolkit.createCustomCursor(pencil,new Point(1, 15),"pencil_cursor");
this.setCursor(pencilcursor);
}catch(Exception exc) {
System.err.println("Unable to create custom cursor.");
}
}
}
}
