How transform anonymous java class to lambda expre

Question

I have an application on JavaFX. In this application, I need to implement, the editor of the column. In the old version of the code worked perfectly:

myColumn.setOnEditCommit(new EventHandler<TableColumn.CellEditEvent<MyRowDataObject, String>>() {
                    @Override
                    public void handle(TableColumn.CellEditEvent<MyRowDataObject, String> t) {
                        ((MyRowDataObject) t.getTableView().getItems().get(
                                t.getTablePosition().getRow())
                        ).setFirstName(t.getNewValue());
                    }
                }
);

but when I tried to rewrite the code using the lambda

myColumn.setOnEditCommit((TableColumn.CellEditEvent event) ->
                ((MyRowDataObject) event.getTableView().getItems().get(event.getTablePosition().getRow())).setEmail(event.getNewValue().toString())
);

I get an error :Error: java: incompatible types: incompatible parameter types in lambda expression Tell me how to specify the type of a lambda expression?

Answer 1

Maybe someone will be interested, turned to compile the code as follows.

 myColumn.setOnEditCommit(event -> {
                final TableColumn.CellEditEvent _evn = (TableColumn.CellEditEvent) event;
                ((MyRowDataObject) _evn.getTableView().getItems().get(_evn.getTablePosition().getRow())).setEmail(_evn.getNewValue().toString());
            });
