Read csv file, display in JavaFX TableView

Java example read csv file and display the content in JavaFX TableView.

To know how to prepare the csv file, and simple read csv file, refer to last post.

JavaFXCSVTableView.java

package javafxcsvtableview;

public class JavaFXCSVTableView extends Application {

public class Record {
//Assume each record have 6 elements, all String

private SimpleStringProperty f1, f2, f3, f4, f5, f6;

public String getF1() {
return f1.get();
}

public String getF2() {
return f2.get();
}

}

}

this.f3 = new SimpleStringProperty(f3);
this.f4 = new SimpleStringProperty(f4);

}

}

private final TableView<Record> tableView = new TableView<>();

private final ObservableList<Record> dataList

@Override

VBox vBox = new VBox();
vBox.setSpacing(10);
vBox.getChildren().add(tableView);

root.getChildren().add(vBox);

primaryStage.setScene(new Scene(root, 700, 250));
primaryStage.show();

readCSV();
}

private void readCSV() {

String CsvFile = "/home/buddy/test/test.csv";
String FieldDelimiter = ",";

BufferedReader br;

try {
br = new BufferedReader(new FileReader(CsvFile));

String line;
while ((line = br.readLine()) != null) {
String[] fields = line.split(FieldDelimiter, -1);

Record record = new Record(fields[0], fields[1], fields[2],
fields[3], fields[4], fields[5]);
dataList.add(record);

}

} catch (FileNotFoundException ex) {
Logger.getLogger(JavaFXCSVTableView.class.getName())
.log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(JavaFXCSVTableView.class.getName())
.log(Level.SEVERE, null, ex);
}

}

public static void main(String[] args) {
launch(args);
}

}
