JavaFX:如何在TableView中选择和删除多个对象

Question

如何在 TableView 中选择和删除多个对象？

public class Controller implements Initializable{
    public TableView<Student> fxClassroom;
    public void deleteStudent(){
        ObservableList<Student> studentSelected, allStudents;
        allStudents = fxClassroom.getItems();
        studentSelected = fxClassroom.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
        studentSelected.forEach(allStudents::remove);
    }
}

但在 Eclipse 中，我不断收到此错误:

Type mismatch cannot convert void to ObservableList

试试这个:

 public class Controller implements Initializable{
    public TableView<Student> fxClassroom;
    @Override
    public void initialize(URL url, ResourceBundle rb) {
      ....
    fxClassroom.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
      ....
    }

        public void deleteStudent(){
            ObservableList<Student> studentSelected, allStudents;
            allStudents = fxClassroom.getItems();
            studentSelected = fxClassroom.getSelectionModel().getSelectedItems();
            allStudents.removeAll(studentSelected);


        }
    }
