Question

Hi all I was hoping that someone would be kind enough to explain to me how I can add a method to buttons in a JoptionPane.
Also can I pplease ask for you to look at this code I think I have stuff something as it is not working the way that I want,
I want to add something like this to the ok button.
String check = LastNameJText.getText()+FirstNameJText.getText();
System.out.println(check);
      if
        //check to see if First & Last name have been entered.
        (check != null){
        return;
        else //create a dialog that shows Title,first & Last Name
         // & ask if you would like to make an new ordre
          String d= System.getProperty("line.separator");
       Object[] options = {"Cancel","OK",};
       int n = JOptionPane.showOptionDialog(null,
       "Do you really want to add a new shoe order for:"+ d +
       (String) TitleComboBox.getSelectedItem()+" "+FirstNameJText.getText()+" "+LastNameJText.getText(),"New Order",
       JOptionPane.YES_OPTION,
       JOptionPane.INFORMATION_MESSAGE,
       null,
       options,
    options[0]);
      if //Check to see if First & Last name text feilds are clear.
(check == null){
return ;
else
   //make sure that all text fields are clear for new order
        ClearAllTextFields();

Answer 1

When I do that i get
"Order.java": Error #: 300 : variable options not found in class epod_1_0.Order at line 2152, column 4
"Order.java": Error #: 300 : variable options not found in class epod_1_0.Order at line 2153, column 4
why would this be ?
This is the code
String check = LastNameJText.getText()+FirstNameJText.getText();
System.out.println(check);
      if
        //check to see if First & Last name have been entered.
        (check != null){
        return;
        else //create a dialog that shows Title,first & Last Name
         // & ask if you would like to make an new ordre
          String d= System.getProperty("line.separator");
      int result = JOptionPane.showOptionDialog(null,
   "Do you really want to add a new shoe order for:"+ d +
   (String) TitleComboBox.getSelectedItem()+" "+FirstNameJText.getText()+
    " "+LastNameJText.getText(),"New Order",
   JOptionPane.YES_OPTION,
   JOptionPane.INFORMATION_MESSAGE,
   null,
   options,
   options[0]);
switch(result){
   case JOptionPane.YES_OPTION: // Add your code for yes
      break;
   case JOptionPane.NO_OPTION: // Add your code for no
     dispose();
      break;
      if //Check to see if First & Last name text feilds are clear.
(check == null){
return ;
else
   //make sure that all text fields are clear for new order
        ClearAllTextFields();
  }
