What's wrong with reading from the console?

Question

MySQL

I recently started learning Java and thought to start making a list type application with contacts using a MySQL database. I connected the database, everything seems to be working properly, but when reading the contact name from the console, the BufferedReader throws an error! Prior to Connecter J for the database, everything worked great. What is the problem ?

Answer 1

attach stacktrace

Answer 2

Without the source, you have to show telepathic abilities. Most likely someone closes the BufferedInputStream somewhere, which is in System.in. Put a breakpoint on the input to the BufferedInputStream.close() method and see how you get there. If you get there too often, make the breakpoint conditional on this == System.in.
