| | static void | drawPoint(java.awt.Graphics g, int x, int y)Draws the point (x, y) in the current color.
g.drawLine(x, y, x, y);
| | public static void | drawStringInRect(java.awt.Graphics g, java.lang.String aString, int x, int y, int width, int height, int justification)Draws aString in the rectangle defined by
(x, y, width, height).
justification specifies the text's justification, one of
LEFT, CENTER, or RIGHT.
drawStringInRect() does not clip to the rectangle, but instead
uses this rectangle and the desired justification to compute the point
at which to begin drawing the text.
