Byte[] character encoding for strings

Question

Hi All,
I tried to convert a string into byte[] using the following code:
byte[] out= [B@30c221;
String encodedString = out.toString();
it gives the output [B@30c221 when i print encodedstring.
but when i convert that encodedstring into byte[] using the following code
byte[] output = encodedString.getBytes();
it gives different output.
is there any character encode needed to give the exact output for this?

Sorry, but the question makes no sense, and neither does your code. byte[] out= [B@30c221;
String encodedString = out.toString(); The first line is syntactically incorrect, and the second should print something like "[B@30c221", which isn't particularly useful. The correct way to convert a String to a byte[] is with the getBytes() method. Be aware that the byte[] will be in the system default encoding, which means you could get different results on different platforms. To remove this platform dependency, you should specify the encoding, like so: byte[] output = encodedString.getBytes("UTF-8"); Why are you doing this, anyway? There are very few good reasons to convert a String to a byte[] within your code; that's usually done by the I/O classes when your program communicates with the outside world, as when you write the string to a file.
