Why when I close a JOptionPane, does It give me an exception?

Question

Sorry if is bad written.

Answer 1

There are dozens of exceptions that can get thrown by the JOptionPane class - show us the code and maybe we can help

Or at least what kind of exceptional you're getting.

Answer 2

OK I'll try to run the code post my findings :)

Answer 3

try{

int num = Integer.parseInt(JOptionPane.showInputDialog("Number: "));
JOptionPane.showMessageDialog(null,"Your number: " + num);

}catch(Exception e){

JOptionPane.showMessageDialog(null, "That's not a number");

}

Answer 4

When I close the JOptionPane that asks for a number, I get the exception I have for an invalid value.
