hex to string conversion...

hi!
is there a way to get the following to work in p69?
import java.util.*;
public class hex2string
{
public static void main(String[] a)
{
String encoding = "iso-8859-1"; // or "utf-8", etc
String hex = "31 32 33 41 42 43";
StringTokenizer st = new StringTokenizer(hex, " \n\r");
int count = st.countTokens();
byte[] buf = new byte[count];
int i = 0;
while (st.hasMoreTokens()) {
buf[i] = Byte.valueOf(st.nextToken(), 16).byteValue();
i++;
}
try {
String text = new String(buf, encoding);
System.out.println(text);
}
catch (Exception e) {
e.printStackTrace();
}
}
}
thanks a lot!

... it is basically just to transform a hexadecimal string like "223E 3C69 6D67 2062" into readable characters.
is there any predefined method to do this in processing??
much appreciated!

yeah, that code is ok, but take out the "import" line, and the "public class" line, and instead of it being a main(), put it inside a function that's used from an applet. processing only deals with applets, and doesn't know how to use the main() method.

you can use a method like what the other poster wrote, but there isn't a built-in way in the currently available releases. in revision 70 and higher there are functions called hex() and unhex() which take care of this.
