Converting byte array to string

[Hari Prasad]

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);
ByteArrayInputS tream byteIn = new ByteArrayInputS tream (dgram.getData
(), 0, dgram.getLength ());

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

String recvString = new String(dgram.ge tData(),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.

Re: Converting byte array to string

Did I understand this completely wrong, or can't you just use the
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.[color=blue]
