I'm trying to design a high score menu for a project I've been maintaining and I would like to be able to use a .txt or .csv file to store and retrieve all of the top scores for this project to be displayed on a highscore menu I built with Scenebuilder but I'm having trouble doing so. So far I've tried using the traditional method of reading from a file but I can't seem to get that to input into the the text area of scenebuilder. Any help is appreciated. Thanks.

}
ObservableList<Highscore> list = FXCollections.observableArrayList(

@Override
public void initialize(URL url, ResourceBundle resourceBundle) {
numColumn.setCellValueFactory(new PropertyValueFactory<Highscore, Integer>("numColumn"));
nameColumn.setCellValueFactory(new PropertyValueFactory<Highscore, String>("nameColumn"));
scoreColumn.setCellValueFactory(new PropertyValueFactory<Highscore, Integer>("scoreColumn"));
table.setItems(list);
}
}
you need to put it in the list, the list is your item source, and it ObservableList so a change in the list will trigger a change in the view, the bind done in: table.setItems(list);
ObservableList<Highscore> list = FXCollections.observableArrayList(
new Highscore(1, 200, "Bob")
);
{
try {
Scanner inputStream = new Scanner(file);
while ((inputStream.hasNext())){
String data = inputStream.next();
Object[] values = data.split("\n");
Object[] values_line = data.split(",");
// Name[0] = (String)values[0];
// Score[0] = (Integer)values[1];
// Num[0] = (Integer)values[2];
list.add(new Highscore(Integer.valueOf(values_line[0].toString()),Integer.valueOf(values_line[1].toString()),values_line[2].toString()));
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
and cleaner:
//list of Highscore items
ObservableList<Highscore> list = FXCollections.observableArrayList();
public void initList(){
try {
Scanner inputStream = new Scanner(file);
while ((inputStream.hasNext())){
String data = inputStream.next();
String[] values_line = data.split(",");
// Name[0] = (String)values[0];
// Score[0] = (Integer)values[1];
// Num[0] = (Integer)values[2];
list.add(new Highscore(Integer.valueOf(values_line[0]),Integer.valueOf(values_line[1]),values_line[2]));
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
@Override
public void initialize(URL url, ResourceBundle resourceBundle) {
//fill the list with values
initList();
numColumn.setCellValueFactory(new PropertyValueFactory<Highscore, Integer>("numColumn"));
nameColumn.setCellValueFactory(new PropertyValueFactory<Highscore, String>("nameColumn"));
scoreColumn.setCellValueFactory(new PropertyValueFactory<Highscore, Integer>("scoreColumn"));
//bind list into the table
table.setItems(list);
