i have a ByteArrayOutputStream with the following content
[13, 10, 45, 45, 95, 78, 101, 120, 116, 80, 97, 114, 116, 0]
i have check whether my stream contains a Empty Line(CRLF) which is represented by 13,10 at the begining.
if it is there i have remove that 13,10.
any body please help me out in doing this
regards

Create an new array of length: old array.length-2 and copy the contents from the old array (starting from index 2) to the new array
Look at the arraycopy(...) method from the System class:
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/System.html
thanks for u r reply.
can u give me a clue on the last parameter(lenght parameter) of arraycopy method actually i am getting exception over there. what can be the length paramater
actually my code follows
ByteArrayOutputStream baos = new ByteArrayOutputStream ();
MutableBodyMimePart mime = MimeHelper.createMimePart(transportMessage, false);
mime.setOutputStream(baos);
mime.writePart();
byte[] wholeMessage = baos.toByteArray();
//here my job starts (removing the CRLF from the baos
ByteArrayOutputStream baos1=new ByteArrayOutputStream(baos.size()-2);
System.arraycopy(baos, 2,baos1,0,baos1.size());
baos1.toByteArray();
baos.close();
baos1.close();
iam getting exception of kind
java.lang.ArrayStoreException

byte[] oldArray = {13, 10, 45, 45, 95, 78, 101, 120, 116, 80, 97, 114, 116, 0};
final int SKIP = 2;
byte[] newArray = new byte[oldArray.length-SKIP];
System.arraycopy(oldArray, SKIP, newArray, 0, newArray.length);
System.out.println(java.util.Arrays.toString(oldArray));
System.out.println(java.util.Arrays.toString(newArray));

I'd say use a dynamic list (like an ArrayList) to store the Bytes you're interested in. When you're done, convert it to an array of primitive bytes (if you want to). If you have more questions on the topic, I suggest creating a thread of your own about it.
