JOptionPane Custom Buttons to return String

Question

I have a method getDate which returns String value. I'd like to add custom buttons but I can't because Eclipse tells me to change method type to int instead of String. What can I do here?

public String getDate(String info){
          return JOptionPane.showInputDialog(null, info, "Date insertion", JOptionPane.PLAIN_MESSAGE);
    }

This is how this InputDialog looks like:

I want this dialog to have let's say Yes/No/Quit buttons and if I understand correctly, code like this should work:

public String getDate(String info){
      return JOptionPane.showOptionDialog(null,info,
                "Date insertion", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE,null,options,
                null);
}

But it says "cannot convert from int to String" and I need it to return String not int.

`JOptionPane.showOptionDialog` return int 0,1,2 depending on selected option . — Madhawa Priyashantha, Apr 09 '16 at 09:47
i don't understand your question clearly .but your first method is correct 2nd one is not correct. — Madhawa Priyashantha, Apr 09 '16 at 10:04
I could do the same thing with 2nd method but I still need program to return the input value and not only 0/1/2 depending on options. Let's say: it returns 0, then it should also return input value. Any other button is exit the program. — programmer3000, Apr 09 '16 at 10:13
what is `options` ?if you show a yes/no option dialog what is the input?? — Madhawa Priyashantha, Apr 09 '16 at 10:19
Nevermind. Is it possible to make an input dialog with custom options by using JOptionPane? I just want that user could input some info and send it by pressing first option. And second option would exit the dialog. — programmer3000, Apr 09 '16 at 10:37

Have the class that invokes JOptionPane.showOptionDialog() get the integer that it returns, and use that to choose the string that you want to return. You cannot change the showOptionDialog() method to return a string, but you can decide, based on the int that it returns, what string you want the caller to get. There's no need for a custom dialog.

public String getDate(String info)
{
  int[] optionStrings = { "Yes", "No", "Cancel" };
  int option = JOptionPane.showOptionDialog(null, info, "Date insertion",
                        JOptionPane.YES_NO_CANCEL_OPTION, 
                        JOptionPane.QUESTION_MESSAGE,null,options,
                        null);
  return optionStrings[option];
}
