Byte returning negative value??

[DanglingPointer]

Whats up with this?

I want to use a plain old unsigned byte 0-255, but the default Java byte type and Byte object are both signed, meaning when I use values > 200 I get value - 256.

I suppose this is something to do with how the byte represents a negative (2s complement?) but i'm not sure of the details.

the code fragment i'm using:

InetAddress ia = null;
byte[] bip = new byte[4];
Byte btmp = null;
String ip = new String();

ia = InetAddress.getByName(hostName);
bip = ia.getAddress();
for ( int i = 0; i < 4; i++ ) {
btmp = new Byte(bip);
if ( i != 3 )
ip += btmp.toString() + &quot;.&quot;;
else
ip += btmp.toString();
}

CHeers.

Please, put your code between [ code ] and [ /code ], otherwhise

 [i]

gets interpreted as &quot;show in italics&quot; by the forum.
What is the problem? What do you want to do with those bytes ?
