javafx getselecteditem returns unexpected output

Question

I am trying to do is get the data from the current selected row on a button click, and return that. However what it returns now is something that seems to be in the format of packagename+ classname+ randomnumbers and letters.

simple.UserDetails@3f59ec1e
simple.UserDetails@210337a8

Random numbers and letters do change when another row is selected. I tried to use thread as example.
Getting selected item from a JavaFX TableView. I would like an answer on how I can achieve the result that I desire. And, if possible be able to save the data in variables too.

Method I use:

  @FXML
    public void getRow() {
        UserDetails row = tableview.getSelectionModel().getSelectedItem();
        System.out.println(row);
    }

The controller class.

Answer 1

You need to say something like row.someMethodorVariableInUserDetails What ever you are trying to return is in your UserDetails class

Look at this example from here

Person person = taview.getSelectionModel().getSelectedItem();
System.out.println(person.getName()); 

In this example they have to say person.somemethod(). In this case person.getName();
