int x = 999;

byte b = (byte)x;// You need to cast explicitly since you are losing precision.

and

byte b = ...;

int x =b;// No casting needed.

OK I'll byte no real pun intended though.

I am having all kinds of trouble outputing to a stream.

I have a value that is an integer 47012 and I

cast it

int foo = 47152

byte bar = (byte) foo;

System.out.println(foo); //just to see if the int is ok

// I am seeing 47152

System.out.println(bar); // in a crazed attempt to get a check of the value

// I am seeing 48

oStream.write(bar);

the file I am writing to is filled instead with

all 30. I know that 30 = 48 in hex so this makes some sense as java is converting the byte to dec 48.

what I dont get is that 47152 = B830 so since I am to collect my data and then convert it to a byte and since I am loosing the top 2 digits how to I preserve them to output to the stream?
