what kind of error checking? like when the user tries to put a king on a 7? you can use a method to check that and if the user is being a moron, then you can display a joptionpane or you can throw one of your own exceptions which will have to be dealt with. something like InvalidMoveException.

For something like that I would say some if else statements would work. Like:

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
if (!card slot is already taken)
{
      //do something
}
else
{
    //do something else
}
if (!card slot is already taken)
{
      //do something
}
else
{
    //do something else
}

Of course it would be cool to experiment making your own exception as EB said.

Thanks for all replies. I just got it working with try and catch exception, my problem was I use try {}catch (IOException e) {} instead of just use catch (Exception e) {}

The input only reads: From <row><coloum> To <row1><coloum1>
Exception prevent any invalid input such as "jslkfjsdlkfjlkd".
