Converting byte array to string

java-programmer, Converting byte array to string Hi,
I am trying to convert a byte array to a string. I am using the
possible ways
but not getting the result.

DatagramPacket dgram = new DatagramPacket(buf, buf.length);
ByteArrayInputStream byteIn = new ByteArrayInputStream (dgram.getData
(), 0, dgram.getLength ());

ObjectInputStream oin = new ObjectInputStream(byteIn);
Object obj = oin.readObject();
String recvString = obj.toString();
DataInputStream dataIn = new DataInputStream (byteIn);
String recvString = dataIn.readLine();

String recvString = new String(dgram.getData(),0,dgram.getLength());
String recvString = dataIn.readLine();

I am trying all these to convert my byte array to a string
But I am getting exception as invalid header.

Can anybody please suggest me.

Regards,
Hari.

How is the String put into the UDP-packet? Is it really
the String-Object serialized or is it just the text?

If the latter, then a simple

String recvString = new String(dgram.getData());
Maybe the explicit specification of the encoding to be used
might be considered in addition to that.

should be enough.

BTW: comp.lang.java doesn't exist anymore.

String(byte [] bytes) constructor?

"just" is the critical word. If you use String(byte [] bytes), the default
encoding will be chosen, which is dependant on you locale.
You should use String(byte [] bytes,String encoding) instead; this makes
the used encoding explicit and reproducable on different machines.
example: new String(ba,"utf-8")
This assumes your data is utf-8 encoded.
google the web for "java encoding" encoding to see which encodings are
avaible.
