Hi Guy's !!! A "User-Defined Object" or a "String Object" is passed from the server to the Client.On the client-side,how should it be determined which type of object has been passed. For Instance,if a String object is passed then InputStream in = new BufferedReader(new InputStreamReader(....)) and readLine() would be used. However,when a user-defined object is passed then ObjectInputStream() and readObject() would be used to obtain the data. How should the type of object passed in the stream be determined ? Pls suggest. Thanks Guy's    More>>

ObjectInputStream() and
readObject() would be used to obtain the data.



How should the type of object passed in the stream be determined ?

Pls suggest.

Get an instance of ObjectInputStream, and do something like


Object result = in.readObject();
if (result instanceof String)
{
    // handle your string
}
else if (result instanceof BlahBlahBlah)
{
    // handle your own type
}
else
{
    // handle unknown types
}
