input = new char[txt.length()+1];
input = txt.toCharArray();
string = new AttributedString(txt, map);
Para = string.getIterator();
txt = new Bidi(Para);
// shape European digits to ARABIC digits if preceding text is Arabic, or
// leave European digits alone if there is no preceding text, or
// preceding text is not Arabic
shaper = NumericShaper.getContextualShaper(NumericShaper.ARABIC,
NumericShaper.EUROPEAN);
shaper.shape(input, 0, txt.lengtht());
txt = txt.copyValueOf(input); //
This is a fully working example for the NumericShaper class
And this is an example for the Bidi class usage

These are some examples on using the TextLayout(extracted from Sun's documentation)
Constructing and drawing a TextLayout and its bounding rectangle:
Graphics2D g = ...;
Point2D loc = ...;
Font font = Font.getFont("Helvetica-bold-italic");
TextLayout layout = new TextLayout("This is a string", font);
g.drawString(layout, loc.getX(), loc.getY());
Rectangle2D bounds = layout.getBounds();
bounds.setRect(bounds.getX()+loc.getX(),
bounds.getY()+loc.getY(),
bounds.getWidth(),
bounds.getHeight())
g.draw(bounds);
Hit-testing a TextLayout (determining which character is at a
particular graphical location):
Point2D click = ...;
TextHitInfo hit = layout.hitTestChar(
(float) (click.getX() - loc.getX()),
(float) (click.getY() - loc.getY()));
Responding to a right-arrow key press:
int insertionIndex = ...;
TextHitInfo next = layout.getNextRightHit(insertionIndex);
if (next != null) {
// translate graphics to origin of layout on screen
g.translate(loc.getX(), loc.getY());
Shape[] carets = layout.getCaretShapes(next.getInsertionIndex());
g.draw(carets[0]);
if (carets[1] != null) {
g.draw(carets[1]);
}
}
Drawing a selection range corresponding to a substring in the source
text. The selected area may not be visually contiguous:
// selStart, selLimit should be relative to the layout,
// not to the source text
int selStart = ..., selLimit = ...;
Color selectionColor = ...;
Shape selection = layout.getLogicalHighlightShape(selStart, selLimit);
// selection may consist of disjoint areas
// graphics is assumed to be tranlated to origin of layout
g.setColor(selectionColor);
g.fill(selection);
Drawing a visually contiguous selection range. The selection range
may correspond to more than one substring in the source text. The
ranges of the corresponding source text substrings can be obtained
with getLogicalRangesForVisualSelection():
TextHitInfo selStart = ..., selLimit = ...;
Shape selection = layout.getVisualHighlightSelection(selStart, selLimit);
g.setColor(selectionColor);
g.fill(selection);
int[] ranges = getLogicalRangesForVisualSelection(selStart, selLimit);
// ranges[0], ranges[1] is the first selection range,
// ranges[2], ranges[3] is the second selection range, etc.
