What is an EOF character?

public abstract int read() throws IOException

Reads the next byte of data from the input stream.

The value byte is returned as an int in the range 0 to 255.

If no byte is available because the end of the stream has been reached,

the value -1 is returned.

This method blocks until input data is available,

the end of the stream is detected, or an exception is thrown.

thanx fr ur responsebut i wanna kno if I take input from the user in form of integers store them in a file and then to read it ,if i use read() it cannot read integers like 23, 287, 24556 and if i use readInt() it cannot trace -1 as eof character

How do you read and write your integers? Did you consider using Data*putStreams for that, because that's what they're there for?

For input and output of integres i'm associating dataInput dataoutputstreams with file streams

Please spell correctly. Anyway, read() reads a byte and yields it as an int as described in the API and cited above. If you want to read a multibyte integer, you have to know how it is composed. If you need textual representation, it is a different situation.

readInt() throws EOFException at end of file.Just like it says in the Javadoc. Nothing there about it returning -1 at EOF.
