To be more specific than my last message, my ultimate goal is to be able
to do something like:
String myString = "ABCDEFG"
Integer myInt = myString.whateverMethod( myString.substring( 1, 2 ))
// should return 66
I can do this by going through a byte[], but was looking for a more
straight forward method, something like VB's asc() function:
In VB:
myInt = asc( mid$( myString, 2,1)) // returns 66
Integer myInt = myString.asc( myString.substring( 1, 2 )) // would
return 66 if the asc() method existed

Hum... I am missing something or you just want to cast a char to a byte/int
in Java?
char x = 'B'; // or "Bravo".charAt(0) if you start with a string
byte y = (byte) x;
System.out.println("y=" + y); // should give you 66
and vice-versa:
char z = (char) y;
System.out.println("z=" + z); // should give you B
The only thing you need to watch is the byte number, I think you get a
number between -128 and +127, so you may need to adjuct depending on your
needs.
BTW I've not tested the code above, I'm just typing it as I speak.

I know "Ascii value" isn't quite the correct term, but it's the only one
I could come up with.
What Im trying to come up with is the simplest way of coming up with the
numeric value associated with a given character, and to go back the
other direction as well. In VB, these are the ASC() and chr()
functions. I know how to get these values by going through a Byte type,
but is there a quicker way to get (for example):
Starting with "B", return 66, or starting with " " (one space), return 32?
Going the other way, 66 should return "B", and 32 should return " ".
Thanks for any suggestions!
