I am creating a pie chart for my Java class and there's a part of a string that I don't know or understand. Can anyone explain it to me? The part in question is bolded.
//Draw rent and utilities slice
startAngle = 0;
arcAngle = (int) (0.40 * DEGREES_IN_CIRCLE);
page.fillArc (x, y, diameter, diameter, startAngle, arcAngle);
page.drawString ("Rent and Utilities (40%)",[b] x + diameter - 15, y + 30)[/b];
