Java JDialog: How to return item (object) selected from a combobox

Question

I have created a jdialog which contains a combobox (see photo ).

The combobox contains items of Delivery class. The date you see in the photo is the value returns from Delivery.toString().

When i press OK, i need to return the Delivery object that is selected from the combobox, to the parent form.

You could use something along the lines of:

    public BillatoDialog extends JDialog(){
       private Delivery selectedDelivery; // Declare selectedDelivery variable

       String selectedDate = comboBox.getSelectedItem();    // Returns the current selected item.
       for (Delivery currentDelivery: deliveryList){        // Loop over a list with all the deliverys. 
          if (currentDelivery.toString()==selectedDate;){  // and break the for when match found.
          selectedDelivery = currentDelivery;          // assign it to selectedDelivery
          break;
          }
       }

      public Delivery getSelectedDelivery(){
         return selectedDelivery;
      }
}

And then in your JPanel

public BillatoPanel extends JPanel(){
   openBillatoDialog();
   getSelectedDelivery();
}
