char hexDigits[] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9','A', 'B', 'C', 'D', 'E', 'F' };
char[] array = { hexDigits[(b >> 4) & 0x0f], hexDigits[b & 0x0f] };
return new String(array);
}
/*
* Returns the hex equivalent of a character
*/

public String charToHex(char c) {
//get the hex of a higher byte
byte hi = (byte) (c >>> 8);
//get the hex equivalent of lower byte
byte lo = (byte) (c & 0xff);
return byteToHex(hi) + byteToHex(lo);
}

Printing the unicode characters to console from java program

I did bit of R and to print the unicode characters from Java.. and finally i found that its a very simple thing and can be done in couple of ways

1) using the java file.encoding system parameter -Dfile.encoding=UTF8. the advantage with this is your program can be run with multiple encodings
2) in java program like

public class InternationalHello {
public static void main (String[] argv) {
String helloInTelugu = "\U0C39\U0C32\UoC4B";

PrintStream out = System.out;
out.println(helloInTelugu );
}
}

cool and easy right..................
