you could try using the scanner class.
does it prompt you for input?

welcome to daniweb :)

apart from scanner , you can also try out a BufferedReader .
i dont really see console being used for this kind of stuff. any particular reason you're using it ?

also , whatever you choose to use , its a good practice to close the io stream after your done with it. traditionally its done inside a finally() block , but with java 7 , a fancy try with resources block can be used.
you can check it out here .

How are you running the program? In particular, if you run it with javaw.exe then there is no console. If so, run it with java.exe instead.
