Java EOFException While Reading Object From A Server (not a file)

Question

So, I write an object to a client like so:

ObjectOutputStream out = new ObjectOutputStream(client.getOutputStream());
out.writeObject(args);
out.close();

And receive the object on the client side like so:

ObjectInputStream in = new ObjectInputStream(connection.getInputStream());

Object objIn;
while(true) {
    if((objIn = in.readObject()) != null) {
        //work with obj
    }
}

I never create an output stream on the client side or an input stream on the server side.

Also, the object I send is serializable.

Thanks for you help!

EDIT: The "duplicate" of this question doesn't help me answer my problem, so this one is not a duplicate.

Answer 1

while(true) {
    if((objIn = in.readObject()) != null) {
        //work with obj
    }
}

Q. Why are you testing for null? Are you planning on sending a null? Because that's the only time you'll ever get one. A. Because you think readObject() returns null at end of stream. Although you've left out the break that would escape the infinite loop.

It doesn't. It throws EOFException. So your loop should look like this:

try
{
    while(true) {
        objIn = in.readObject();
        //work with obj
    }
}
catch (EOFException exc)
{
    // end of stream
}
finally
{
    in.close();
}
