Error Checking for user input
 

Hello all, is that possible to help me out with Error Checking for user input? I am developing a peg solitaire program and now need a error checking for user input or for input file.

Either use try and catch.. or making another method.. can anyone give a me a hint or help me out here please.

Regards

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:

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".
