Hi,

I keep getting a compiler warning saying that getBytes has been
deprocated and that I should stop using it, the thing is I cant seem to
figure out what I am supposed to replace it with, Sun's API reference didnt
help.

I'm trying to write some code to implement a few e-mail protocols so
getBytes is kind of useful!

Thanks in advance for any help,

JDK 1.1.3 API ref. says the following about String.getBytes(int, int,
byte, int) - apparently this is the only getBytes that is deprecated.

If you read the 'getBytes' entry, it tells you exactly what you should replace
it with. From the API docs for String.getBytes(int, int, byte[], int) :

>Note: getBytes() is deprecated. This method does not properly convert characters

So code that used to say:

String s;
:
:
int len = 1024;
byte b[] = new byte[len];
s.getBytes(0, len, b, 0);

should be replaced by:

String s;
:
:
byte b[] = s.getBytes();
int len = b.length;
