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

It will always go in else condition even if cancel button is pressed. Check for,

else if(input == JOptionPane.CANCEL_OPTION){
   System.out.println("Cancel is pressed");
}

add above code before last else statement explicitly, and handle cancel button pressed there.

Answer 2

I had this same issue, and I solved it as follow:

if(input != null){
    if(!input.isEmpty()){
     // Do whatever...
    }
}

So, I basically moved the null test before testing if the user has entered some input. Hope this helped!

Answer 3

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();
}
