Hi All,

I am reading a vector written to a file using ObjectInputStream. Please see the code below

1.FileInputStream istream = new FileInputStream(File);
2.ObjectInputStrea ostream = new ObjectInputStream(istream);
3.Vector v = (Vector) ostream.readObject();

When the file is empty the above code throws (at the third line above) EOFException.

How can i check for EOF condition here? Please help me in solving the issue.

Thanks in advance.
Binu Mathew.

How about this.

try{ //
}catch(EOFException e){
System.out.println("File is possibly empty.");
// or
// throw new Exception("File is possibly empty.");
// with getMessage() method for the caught Exception.

Byte length is known if you use "another" FileInputStream object (e.g., _istream) and the read() method, with counting block
