Clicking the cancel button showInputDialogue

Question

I have a question in regards to pressing the cancel button of my inputDialoguebox. I have asked a similar question before so I apologize if I seem to repeat myself.

Answer 1

When you click on the Cancel Button of the showInputDialog(...) , you always get a null value, for which no condition is satisfied, hence a new connection is always established. So you can add this condition like this :

if(input == null || (input != null && ("".equals(input))))   
{
    throw new EmptyFieldsException();
}
