This method sets the user clip, which is independent of the
clipping associated with device bounds and window visibility.
This method can only be used to make the current clip smaller.
To set the current clip larger, use any of the setClip methods.

Graphics
object cannot be used after
dispose
has been called.
When a Java program runs, a large number of Graphics
objects can be created within a short time frame.
Although the finalization process of the garbage collector
also disposes of the same system resources, it is preferable
to manually free the associated resources by calling this
method rather than to rely on a finalization process which
may not run to completion for a long period of time.
Graphics objects which are provided as arguments to the
paint
and update
methods
of components are automatically released by the system when
those methods return. For efficiency, programmers should
call dispose
when finished using
a Graphics
object only if it was created
directly from a component or another Graphics
object.

shape
- - the Shape to be renderedpublic void drawArc(int x, int y, int width, int height, int startAngle, int arcAngle)
The resulting arc begins at startAngle
and extends
for arcAngle
degrees, using the current color.
Angles are interpreted such that 0 degrees
is at the 3 o'clock position.
A positive value indicates a counter-clockwise rotation
while a negative value indicates a clockwise rotation.
The center of the arc is the center of the rectangle whose origin
is (x, y) and whose size is specified by the
width
and height
arguments.
The resulting arc covers an area
width + 1
pixels wide
by height + 1
pixels tall.
The angles are specified relative to the non-square extents of the bounding rectangle such that 45 degrees always falls on the line from the center of the ellipse to the upper right corner of the bounding rectangle. As a result, if the bounding rectangle is noticeably longer in one axis than the other, the angles to the start and end of the arc segment will be skewed farther along the longer axis of the bounds.

shape
- - the Shape to be filledpublic void fillArc(int x, int y, int width, int height, int startAngle, int arcAngle)
The resulting arc begins at startAngle
and extends
for arcAngle
degrees.
Angles are interpreted such that 0 degrees
is at the 3 o'clock position.
A positive value indicates a counter-clockwise rotation
while a negative value indicates a clockwise rotation.
The center of the arc is the center of the rectangle whose origin
is (x, y) and whose size is specified by the
width
and height
arguments.
The resulting arc covers an area
width + 1
pixels wide
by height + 1
pixels tall.
The angles are specified relative to the non-square extents of the bounding rectangle such that 45 degrees always falls on the line from the center of the ellipse to the upper right corner of the bounding rectangle. As a result, if the bounding rectangle is noticeably longer in one axis than the other, the angles to the start and end of the arc segment will be skewed farther along the longer axis of the bounds.

public void fillPolygon(int[] xPoints, int[] yPoints, int nPoints)
This method draws the polygon defined by nPoint
line
segments, where the first nPoint - 1
line segments are line segments from
(xPoints[i - 1], yPoints[i - 1])
to (xPoints[i], yPoints[i])
, for
1 ≤ i ≤ nPoints
.
The figure is automatically closed by drawing a line connecting
the final point to the first point, if those points are different.
The area inside the polygon is defined using an even-odd fill rule, also known as the alternating rule.
