Which group? This was posted to three groups
separately, which is usually called a multi-post.

Please refrain from multi-posting, in future.

This is a very popular homework assignment. Was this homework?

> i [sic] hope to find solution for this problem,

Post the solution you've already tried and tell us what /specific/ difficulty
you're having.

Now I read this post, I am wonderring if you actually
meant 'farsi'. Searches will go better with correctly
spelt search terms. While I'm here, I will ask that
you put a single Upper Case letter at the start of
each sentence, to make it easier to read.

This code is off the top of my head, and not tested or compiled:

<code>
public static char convertToArabicDigit(int i) {
switch(i) {
case 0:
return '\u0660';
case 1:
return '\u0661';
case 2:
return '\u0662';
case 3:
return '\u0663';
case 4:
return '\u0664';
case 5:
return '\u0665';
case 6:
return '\u0666';
case 7:
return '\u0667';
case 8:
return '\u0668';
case 9:
return '\u0669';
default:
throw new IllegalArgumentException();
}
}
</code>

Or the much shorter variant (w/o checking):
return 0x660 + i;

You'd need to downcast that to char, and presumably mask or error-check the
value of 'i'.

The switch variant is longer, but that is not important. It's safer and,
chances are, faster. And it's only significantly longer in the source code,
where length is not harmful.

A clever approach might use a Map< Integer, Character>. "Clever" != "good".
("Clever" != "bad", but "clever" == "risky".)

Switches are not necessarily faster: take converting '0' to 0:

The probable fastest is way is (char)(c & 0xf) - it is a simple bit
mask. A switch, by contrast, is probably at best going to calculate an
offset and then load a value to return.

Changing numeric numbers by manipulating the relative zero character
makes the most sense to me, because of the way Unicode treats digits. It
is easiest for me to see '(Farsi 0)' + i and recognize what it does as
opposed to a switch with '(Farsi 0)' ... '(Farsi 9)', simply because
that's how I process information.

To each his own, I guess.

First, char is 16 bits wide, so don't you mean
(char) (c & 0xffff)?

Second, code points aren't always exactly 16 bits wide. I don't even know if
that affects this matter but it might affect someone parsing a String.

i would like to thank you for you help... i tryed your code... but the
returned result well be ? for any number... my operating system is
windows xp and i using jbuilder7 for writing and testing java codes...
i think your code is correct but the problem in unicode... can you
tell me how can i make my program accept the '\u066*' unicode and what
is the main name of this unicode?

thank you very much.

The problem might not be the code but the font you use to display the result.

Java programs must accept '\u' characters by definition, so that cannot be the
problem.

Also, if you are receiving Strings from external sources, or sending them to
external sources, be aware of encoding issues.

Where are you seeing these "?" characters? Are you using
System.out.println() to display them? If so, the problem may be that your
console doesn't support displaying Arabic characters. As a test, you can
try writing the characters to a file (using a suitable encoding such as
UTF-8 -- ASCII would *not* be suitable), and then using a hex editor to
open the file and check that the correct set of bytes were written.

As Lew mentioned, part of the Java specification requires all
compilers to accept the '\u066*' codes, so that probably isn't an issue
worth investigating.

Not sure I understand this question. I got the information from the
PDF file at http://www.unicode.org/charts/PDF/U0600.pdf and these sequence
of characters are titled "Arabic-Indic digits". Below that, they write
"These digits are used with Arabic proper; for languages of Iran,
Pakistan, and India, see the Eastern Arabic-Indic digits at 06F0..06F9."
The characters themselves are named "ARABIC-INDIC DIGIT ZERO",
"ARABIC-INDIC DIGIT ONE", etc.

Look into class
java.awt.font.NumericShaper
Specifically, the shape() method(s).

I have never used it myself, but as far as I can tell from the JavaDoc, it is
intended for just that purpose.
