java.lang.NumberFormatException: For input stream:jav

[osval]

I'm working on a Mail Client using SMTP protocol.
The code compiles fine but when I run the code with valid inputs and click the send button an exception appears

Code:

 
java.lang.NumberFormatException: For input stream:"jav".

any ideas?

Can you paste your code?

I solved my problem!
in the line

Code:

int code = Integer.parseInt(reply.substring(0,3));

That has to be what's throwing the NumberFormat exception. I had to put a try block in there and return -1 if an exception is indeed thrown.

output the substring before you try to parse it so you can see exactly what it's trying to parse.
