FileInputStream istream = new FileInputStream("t.tmp");
DataInputStream p2 = new DataInputStream(istream);
int i = p2.readInt(); // reads 4 byte value
int i1 = p2.readShort(); // reads 2 byte value
char c = (char)p2.readByte(); // reads 1 byte char

Yes.. it worked perfectly..
What does it mean to be "Always On"?

Then why did you give it a "D"? I'm curious. You must have expected more. I thought that the supplied code was sufficient an answer. Obviously I was mistaken.

I gave it a 'B'.... The other question on conversions
from a binary file using ObjectInputStream was given a
'D'..not this one.. I use the above information on the
same binary file..

My mistake, I confused the questions. I'm still disappointed that you graded the other question a "D" .. It is kind of a matter of pride. Yours is the only D I've gotten thus far as an "expert" here. Oh, well...
